&lt;div&gt;
&lt;b&gt;&lt;span style=&quot;font-size: large;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/b&gt;&lt;/div&gt;
&lt;div&gt;
Para sumar y/o restar fracciones con el mismo denominador, se deja el mismo denominador y se realiza la operación en los numeradores&lt;/div&gt;
&lt;div&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div&gt;
&lt;b&gt;Ejemplos:&amp;nbsp;&lt;/b&gt;&lt;/div&gt;
&lt;div&gt;
&lt;b&gt;&lt;br /&gt;&lt;/b&gt;&lt;/div&gt;
&lt;div&gt;
\[\large\frac{2}{7}+\frac{8}{7}=\frac{2+8}{7}=\color{red}{\frac{10}{7}}\]&lt;br /&gt;
&lt;a name=&#39;more&#39;&gt;&lt;/a&gt;&lt;/div&gt;
&lt;div&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div&gt;
\[\large\frac{16}{9}-\frac{13}{9}=\frac{16-13}{9}=\color{red}{\frac{3}{9}}\]&lt;/div&gt;
&lt;div&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div&gt;
\[\large\frac{21}{15}-\frac{7}{15}+\frac{6}{15}=\frac{21-7+6}{15}=\color{red}{\frac{20}{15}}\]&lt;/div&gt;
&lt;div&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div&gt;
&lt;b&gt;&lt;span style=&quot;font-size: large;&quot;&gt;Sumas y restas de fracciones con diferente denominador&lt;/span&gt;&lt;/b&gt;&lt;/div&gt;
&lt;div&gt;
&lt;b&gt;&lt;span style=&quot;font-size: large;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/b&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
Para sumar y/o restar fracciones con diferente denominador, se debe hallar el m.c.m(mínimo común múltiplo) de los denominadores, luego se deja el m.c.m (mínimo común múltiplo) como denominador, y a cada una de las fracciones el m.c.m. se divide entre el denominador de las fracciones y después se multiplica por el numerador, así sucesivamente hasta obtener las fracciones equivalentes para obtener suma y resta de fracciones con el mismos denominador.&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;b&gt;Ejemplo&lt;/b&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;b&gt;&lt;br /&gt;&lt;/b&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
\[\large\frac{2}{4}+\frac{8}{16}-\frac{7}{2}\]&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
Lo primero que debemos hacer, es hallar el m.c.m. de los denominadores, es decir en este caso hallar el m.c.m. de 4, 16, 2&amp;nbsp;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
\[\left.\begin{matrix} 4 &amp;amp; 16 &amp;amp; 2\\ 2 &amp;amp; 8 &amp;amp; 1\\ 1 &amp;amp; 4 &amp;amp; 1\\ 1 &amp;amp; 2 &amp;amp; 1\\ 1 &amp;amp; 1 &amp;amp; 1 \end{matrix}\right|\begin{matrix} 2\\ 2\\ 2\\ 2\\ - \end{matrix}\]&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
\[2 \times 2 \times 2 \times 2=\color{red}{16}\]&amp;nbsp;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
16 es el m.c.m y seria el denominador común , ahora hallaremos el numerador para cada una de las fracciones para convertirlas en equivalentes.&lt;/div&gt;
&lt;div&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
Ahora a cada una de las fracciones , 16 (el m.c.m de los denominadores) lo multiplicamos por el denominador y divimos por el numerador , el numero de resultado queda como numerador y como denominador el m.c.m. (16).&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
\[­equivalencia\leftrightarrow \]&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
\[\large\frac{2}{4}=&amp;gt; \color{red}{16} \div 4 \times 2 = 32\]&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
\[\large\frac{2}{4}­\leftrightarrow \frac{8}{16}\]&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
\[\large\frac{8}{16}=&amp;gt; \color{red}{16} \div 16 \times 8 = 8\]&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
\[\large\frac{8}{16}­\leftrightarrow \frac{8}{16}\]&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
\[\large\frac{7}{2}=&amp;gt; \color{red}{16} \div 2 \times 7 = 56\]&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
\[\large\frac{7}{2}­\leftrightarrow \frac{56}{16}\]&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
Entonces la suma de fracciones queda de la siguiente manera:&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
\[\large\frac{8}{16}+\frac{8}{16}-\frac{56}{16}\]&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
Ahora ya que las fracciones son equivalentes teniendo encuenta que contienen mismo denominador &amp;nbsp;, solo queda operar los numeradores.&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
\[\large\frac{8+8-56}{16}\]&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
\[\large\frac{-40}{16}\]&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
Ahora simplificando el resultado es:&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
\[\color{red}{-\frac{5}{2}}\]&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;b&gt;EJERCICIOS&lt;/b&gt;&lt;br /&gt;
&lt;b&gt;&lt;br /&gt;&lt;/b&gt;
&lt;b&gt;A)&amp;nbsp;&lt;/b&gt;\[\large\frac{8}{3}+\frac{7}{3}\]&lt;br /&gt;
&lt;br /&gt;
&lt;b&gt;B)&amp;nbsp;&lt;/b&gt;\[\large\frac{7}{10}+\frac{15}{10}\]&lt;br /&gt;
&lt;br /&gt;
&lt;b&gt;C)&lt;/b&gt;&amp;nbsp;\[\large\frac{3}{4}+\frac{1}{6}-\frac{1}{18}\]&lt;br /&gt;
&lt;br /&gt;
&lt;b&gt;D)&amp;nbsp;&lt;/b&gt;\[\large\frac{4}{6}-\frac{7}{2}-\frac{1}{7}\]&lt;br /&gt;
&lt;br /&gt;
&lt;b&gt;E)&lt;/b&gt;&amp;nbsp;\[\frac{4}{2}-\frac{7}{2}+\frac{1}{2}\]&lt;br /&gt;
&lt;br /&gt;
&lt;b&gt;F)&amp;nbsp;&lt;/b&gt;\[\frac{19}{2}-\frac{1}{6}+\frac{1}{4}\]&lt;br /&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;br /&gt;

&lt;br /&gt;
&lt;b&gt;&lt;span style=&quot;font-size: large;&quot;&gt;Ley para la Suma y Resta:&lt;/span&gt;&lt;/b&gt;&lt;br /&gt;
&lt;br /&gt;
1. Si los valores tienen el mismo signo se suma y el signo se conserva.&lt;br /&gt;
&lt;a name=&#39;more&#39;&gt;&lt;/a&gt;&lt;br /&gt;
&amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp;Ejemplo:&lt;br /&gt;
&amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp;\[7+2=9\]&lt;br /&gt;
&amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp;\[\left(-5\right)+\left(-8\right)=-13\]&lt;br /&gt;
&lt;br /&gt;
2. Si los numeros tienen Distintos signos, se realiza la resta y al resultado se le coloca el signo del numero con mayor valor absoluto.&lt;br /&gt;
&amp;nbsp; &amp;nbsp; &amp;nbsp; Ejemplo:&lt;br /&gt;
&amp;nbsp; &amp;nbsp; &amp;nbsp;&amp;nbsp;\[\left(-4\right)+8=4\]&lt;br /&gt;
&amp;nbsp; &amp;nbsp; &amp;nbsp; Se resta 8 - 4 y como el el numero mayor de la operación es positivo el resultado es positivo que &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; es 4.&lt;br /&gt;
&lt;br /&gt;
&lt;b&gt;&lt;span style=&quot;font-size: large;&quot;&gt;Ley para la multiplicación:&lt;/span&gt;&lt;/b&gt;&lt;br /&gt;
&lt;b&gt;&lt;span style=&quot;font-size: large;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/b&gt;
&lt;br /&gt;
&lt;table border=&quot;1px&quot; style=&quot;text-align: center; width: 300px;&quot;&gt;
  &lt;tbody&gt;
&lt;tr&gt;
    &lt;th class=&quot;tg-031e&quot;&gt;+&lt;/th&gt;
    &lt;th class=&quot;tg-031e&quot;&gt;por&lt;/th&gt;
    &lt;th class=&quot;tg-031e&quot;&gt;+&lt;/th&gt;
    &lt;th class=&quot;tg-031e&quot;&gt;=&lt;/th&gt;
    &lt;th class=&quot;tg-yw4l&quot;&gt;+&lt;/th&gt;
  &lt;/tr&gt;
&lt;tr&gt;
    &lt;td class=&quot;tg-031e&quot;&gt;&lt;div style=&quot;text-align: center;&quot;&gt;
-&lt;/div&gt;
&lt;/td&gt;
    &lt;td class=&quot;tg-031e&quot;&gt;&lt;div style=&quot;text-align: center;&quot;&gt;
por&lt;/div&gt;
&lt;/td&gt;
    &lt;td class=&quot;tg-031e&quot;&gt;&lt;div style=&quot;text-align: center;&quot;&gt;
-&lt;/div&gt;
&lt;/td&gt;
    &lt;td class=&quot;tg-031e&quot;&gt;&lt;div style=&quot;text-align: center;&quot;&gt;
=&lt;/div&gt;
&lt;/td&gt;
    &lt;td class=&quot;tg-yw4l&quot;&gt;&lt;div style=&quot;text-align: center;&quot;&gt;
+&lt;/div&gt;
&lt;/td&gt;
  &lt;/tr&gt;
&lt;tr&gt;
    &lt;td class=&quot;tg-031e&quot;&gt;&lt;div style=&quot;text-align: center;&quot;&gt;
+&lt;/div&gt;
&lt;/td&gt;
    &lt;td class=&quot;tg-031e&quot;&gt;&lt;div style=&quot;text-align: center;&quot;&gt;
por&lt;/div&gt;
&lt;/td&gt;
    &lt;td class=&quot;tg-031e&quot;&gt;&lt;div style=&quot;text-align: center;&quot;&gt;
-&lt;/div&gt;
&lt;/td&gt;
    &lt;td class=&quot;tg-031e&quot;&gt;&lt;div style=&quot;text-align: center;&quot;&gt;
=&lt;/div&gt;
&lt;/td&gt;
    &lt;td class=&quot;tg-yw4l&quot;&gt;&lt;div style=&quot;text-align: center;&quot;&gt;
-&lt;/div&gt;
&lt;/td&gt;
  &lt;/tr&gt;
&lt;tr&gt;
    &lt;td class=&quot;tg-031e&quot;&gt;&lt;div style=&quot;text-align: center;&quot;&gt;
-&lt;/div&gt;
&lt;/td&gt;
    &lt;td class=&quot;tg-031e&quot;&gt;&lt;div style=&quot;text-align: center;&quot;&gt;
por&lt;/div&gt;
&lt;/td&gt;
    &lt;td class=&quot;tg-031e&quot;&gt;&lt;div style=&quot;text-align: center;&quot;&gt;
+&lt;/div&gt;
&lt;/td&gt;
    &lt;td class=&quot;tg-031e&quot;&gt;&lt;div style=&quot;text-align: center;&quot;&gt;
=&lt;/div&gt;
&lt;/td&gt;
    &lt;td class=&quot;tg-yw4l&quot;&gt;&lt;div style=&quot;text-align: center;&quot;&gt;
+&lt;/div&gt;
&lt;/td&gt;
  &lt;/tr&gt;
&lt;/tbody&gt;&lt;/table&gt;
&lt;br /&gt;
Ejemplos:&lt;br /&gt;
&lt;br /&gt;
&lt;div&gt;
\[5\times2=10\]&lt;/div&gt;
&lt;div&gt;
\[\left(-3\right)\times\left(-7\right)=21\]&lt;/div&gt;
&lt;div&gt;
\[\left(-4\right)\times8=-32\]&lt;/div&gt;
&lt;div&gt;
\[9\times\left(-6\right)=-54\]&lt;br /&gt;
&lt;br /&gt;
&lt;b&gt;Como resolver Polinomios Aritmeticos&lt;/b&gt;&lt;br /&gt;
&lt;b&gt;&lt;br /&gt;&lt;/b&gt;
Cuando se resuelve polinomios aritméticos se utilizan ( paréntesis ), [corchetes] y {llaves} ; es un sistema anidado por medio de las cuatro operaciones básicas&lt;br /&gt;
&lt;br /&gt;
&lt;b&gt;&lt;i&gt;Reglas para resolver un sistema aritmético&lt;/i&gt;&lt;/b&gt; &lt;br /&gt;
&lt;br /&gt;
1. Cuando un sistema anidado por signos de agrupación esta precedido por un signo +, los números quedan igual.&lt;br /&gt;
&amp;nbsp; &amp;nbsp; Ejemplo:&lt;br /&gt;
&lt;br /&gt;
\[ {\color{red}+\left(9-2\right)}\]&lt;br /&gt;
&lt;br /&gt;
&amp;nbsp; &amp;nbsp; como esta precedido por el signo + (mas)&amp;nbsp;el sistema dentro de los paréntesis queda igual y estos se eliminan quedando así:&lt;br /&gt;
&lt;br /&gt;
\[9-2\]&lt;br /&gt;
&lt;br /&gt;
2. Cuando un sistema anidado esta precedido por un signo - (menos), los numeros cambian de signo.&lt;br /&gt;
&lt;br /&gt;
&amp;nbsp; &amp;nbsp; Ejemplo:&lt;br /&gt;
&lt;br /&gt;
\[{\color{red}-\left[-8+2\right]}\]&lt;br /&gt;
&lt;br /&gt;
como esta precedido por el signo - (menos)&amp;nbsp;el sistema dentro de los paréntesis cambian de signo y estos se eliminan.&lt;br /&gt;
&lt;br /&gt;
\[+8-2\]&lt;br /&gt;
&lt;br /&gt;
3. Cuando se resuelve un polinomio aritmético, se desarrolla de adentro hacia fuera resolviendo primero los signos.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;b&gt;&lt;span style=&quot;font-size: large;&quot;&gt;Resolviendo el primer polinomio aritmético&lt;/span&gt;&lt;/b&gt;&lt;br /&gt;
&lt;br /&gt;
Resolver el siguiente polinomio&lt;br /&gt;
\[-\left\{2+3+\left[-7+8-\left(-4+5\right)\right]\right\}\]&lt;br /&gt;
&lt;br /&gt;
Lo primero es eliminar los signos de agrupacion, es decir eliminar:&lt;br /&gt;
Primero los (paréntesis)&lt;br /&gt;
Segundo los [corchetes]&lt;br /&gt;
Tercero las {llaves}&lt;br /&gt;
&lt;br /&gt;
Teniendo claro lo anterior&lt;br /&gt;
&lt;br /&gt;
&amp;nbsp;Primero eliminamos los paréntesis () resolviendo los signos, &amp;nbsp;\[-\left\{2+3+\left[-7+8-\color{red} {\left(-4+5\right)}\right]\right\}\] analicemos que lo que esta dentro del paréntesis esta precedido del signo -(menos) por lo tanto, lo de adentro cambia de signo.&lt;br /&gt;
&lt;br /&gt;
El polinomio aritmético queda de la siguiente forma:&amp;nbsp;\[-\left\{2+3-\left[-7+8+4-5\right]\right\}\]&lt;br /&gt;
&lt;br /&gt;
Segundo eliminamos los corchetes [ ] resolviendo los signos&amp;nbsp;\[-\left\{2+3-\color{red}{\left[-7+8+4-5\right]}\right\}\] analicemos que lo que esta dentro de los corchetes esta precedido del signo - (menos) por lo tanto cambia de signo.&lt;br /&gt;
&lt;br /&gt;
El polinomio aritmético queda de la siguiente forma:&amp;nbsp;\[-\left\{2+3+7-8-4+5\right\}\]&lt;br /&gt;
&lt;br /&gt;
Tercero eliminamos las llaves { } resolviendo los signos \[-\color{red}{\left\{2+3+7-8-4+5\right\}}\] analicemos que lo que esta dentro de las llaves este precedido del signo -(menos) por lo tanto cambia de signo.&lt;br /&gt;
&lt;br /&gt;
El polinomio queda de la siguiente manera en una operación común&lt;br /&gt;
&lt;br /&gt;
\[-2-3-7+8+4-5\]&lt;br /&gt;
&lt;br /&gt;
Ahora es importante operar de izquierda a la derecha siguiendo el orden de cada uno.&lt;br /&gt;
Para ir adquiriendo mas habilidad podemos operar de a dos números teniendo en cuenta que se debe seguir el orden mencionado.&lt;br /&gt;
&lt;br /&gt;
Entonces:&lt;br /&gt;
&lt;br /&gt;
\[\color{red}{-2-3}-7+8+4-5\]&lt;br /&gt;
&lt;br /&gt;
primero resolvamos \[-2-3 =- 5\] &amp;nbsp;queda de la siguiente manera \[\color{red}{-5}-7+8+4-5\]&lt;br /&gt;
&lt;br /&gt;
Ahora operamos el siguiente numero a la derecha&amp;nbsp;\[\color{red}{-5-7}+8+4-5\] resolvemos \[-5-7 =-12\] queda de la siguiente manera \[\color{red}{-12}+8+4-5\]&lt;br /&gt;
&lt;br /&gt;
Ahora operamos el siguiente numero a la derecha&amp;nbsp;\[\color{red}{-12+8}+4-5\] resolvemos \[-12+8=-4\] queda de la siguiente manera &amp;nbsp;\[\color{red}{-4}+4-5\]&lt;br /&gt;
&lt;br /&gt;
Ahora operamos el siguiente numero a la derecha&amp;nbsp;\[\color{red}{-4+4}-5\] resolvemos \[-4+4=0\] queda de la siguiente manera \[\color{red}{0}-5\] , ya podemos operar los dos números faltantes y \[0-5=-5\] , entonces el resultado del polinomio es \[\bf \color{red} {-5}\]&amp;nbsp; &lt;br /&gt;
&lt;br /&gt;

&lt;b&gt;&lt;span style=&quot;font-size: x-large;&quot;&gt;Ejercicios&lt;/span&gt;&lt;/b&gt;&lt;br /&gt;
&lt;br /&gt;
&lt;b&gt;&lt;span style=&quot;font-size: large;&quot;&gt;a)&lt;/span&gt; &amp;nbsp;&lt;/b&gt;\[9-7+\left\{-2+3-\left[4-2+\left(3+2\right)-7\right]+8\right\}\]&lt;br /&gt;
&lt;br /&gt;
&lt;b&gt;&lt;span style=&quot;font-size: large;&quot;&gt;b)&lt;/span&gt;&amp;nbsp;&lt;/b&gt;\[-\left\{2-4+\left[-7-3-\left(9+3\right)\right]\right\}\]&lt;br /&gt;
&lt;br /&gt;
&lt;b&gt;&lt;span style=&quot;font-size: large;&quot;&gt;c)&lt;/span&gt;&amp;nbsp;&lt;/b&gt;\[4+\left\{2+3-\left[2-\left(2-3\right)+\left(7-8\right)\right]\right\}\]&lt;br /&gt;

&lt;span style=&quot;font-family: &amp;quot;arial&amp;quot; , &amp;quot;helvetica&amp;quot; , sans-serif;&quot;&gt;1. Una familia desea realizar un viaje por tres ciudades de Colombia para lo cual han realizado una cotización en una agencia de turismo. La agencia les presenta el siguiente cuadro con la información del valor por noche y por persona en cada ciudad.&lt;/span&gt;&lt;/span&gt;&lt;br /&gt;

&lt;span style=&quot;font-family: &amp;quot;arial&amp;quot; , &amp;quot;helvetica&amp;quot; , sans-serif;&quot;&gt;&lt;b&gt;a.&lt;/b&gt; Teniendo en cuenta la información dada por la agencia, la familia desea calcular el costo del hospedaje por persona si se quedan 3 días en Cartagena, 5 en Santa Marta y 4 en Barranquilla. Represente la situación anterior como una operación entre matrices para determinar el costo del viaje para cada una de las opciones de hospedaje.&amp;nbsp;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both;&quot;&gt;
&lt;span style=&quot;font-family: &amp;quot;arial&amp;quot; , &amp;quot;helvetica&amp;quot; , sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both;&quot;&gt;
&lt;span style=&quot;font-family: &amp;quot;arial&amp;quot; , &amp;quot;helvetica&amp;quot; , sans-serif;&quot;&gt;R/ Lo primero es sacar la matriz del cuadro cuadro anterior; a esta matriz la llamaremos matriz A.&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both;&quot;&gt;
&lt;span style=&quot;font-family: &amp;quot;arial&amp;quot; , &amp;quot;helvetica&amp;quot; , sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both;&quot;&gt;
&lt;span style=&quot;font-family: &amp;quot;arial&amp;quot; , &amp;quot;helvetica&amp;quot; , sans-serif;&quot;&gt;\[A=\begin{bmatrix} 80000 &amp;amp; 70000 &amp;amp; 50000\\ 76000 &amp;amp; 63000 &amp;amp; 45000\\ 72000 &amp;amp; 56000 &amp;amp; 38000 \end{bmatrix}\]&amp;nbsp;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both;&quot;&gt;
&lt;span style=&quot;font-family: &amp;quot;arial&amp;quot; , &amp;quot;helvetica&amp;quot; , sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;

&lt;span style=&quot;font-family: &amp;quot;arial&amp;quot; , &amp;quot;helvetica&amp;quot; , sans-serif;&quot;&gt;Ahora lo que hacemos es sacar una matriz B con los los días de hospedaje en las tres ciudades; me sale una matriz 3x1 .&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both;&quot;&gt;
&lt;span style=&quot;font-family: &amp;quot;arial&amp;quot; , &amp;quot;helvetica&amp;quot; , sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;

&lt;span style=&quot;font-family: &amp;quot;arial&amp;quot; , &amp;quot;helvetica&amp;quot; , sans-serif;&quot;&gt;Ahora procedemos a realizar una multiplicación matriz A x B = AB ; teniendo en cuenta que la matriz A es de dimensión 3x3 y la Matriz B es de dimensión 3x1, y el numero de columnas de la matriz A es igual al numero de filas de la matriz B es posible realizar dicha operación.&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both;&quot;&gt;
&lt;span style=&quot;font-family: &amp;quot;arial&amp;quot; , &amp;quot;helvetica&amp;quot; , sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;

&lt;span style=&quot;font-family: &amp;quot;arial&amp;quot; , &amp;quot;helvetica&amp;quot; , sans-serif;&quot;&gt;Entonces el resultado seria una matriz de dimension 3x1 llamada AB.&amp;nbsp;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both;&quot;&gt;
&lt;span style=&quot;font-family: &amp;quot;arial&amp;quot; , &amp;quot;helvetica&amp;quot; , sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both;&quot;&gt;
&lt;span style=&quot;font-family: &amp;quot;arial&amp;quot; , &amp;quot;helvetica&amp;quot; , sans-serif;&quot;&gt;\[AB=\begin{bmatrix} a_{11}\\ a_{21}\\ a_{31} \end{bmatrix}\]&lt;/span&gt;&lt;/div&gt;

&lt;span style=&quot;font-family: &amp;quot;arial&amp;quot; , &amp;quot;helvetica&amp;quot; , sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both;&quot;&gt;
&lt;span style=&quot;font-family: &amp;quot;arial&amp;quot; , &amp;quot;helvetica&amp;quot; , sans-serif;&quot;&gt;Procedemos a realizar la operaciones&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both;&quot;&gt;
&lt;span style=&quot;font-family: &amp;quot;arial&amp;quot; , &amp;quot;helvetica&amp;quot; , sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both;&quot;&gt;
&lt;span style=&quot;font-family: &amp;quot;arial&amp;quot; , &amp;quot;helvetica&amp;quot; , sans-serif;&quot;&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both;&quot;&gt;
&lt;span style=&quot;font-family: &amp;quot;arial&amp;quot; , &amp;quot;helvetica&amp;quot; , sans-serif;&quot;&gt;\[a_{11}=(80000*3)+(70000*5)+(50000*4)=240000+350000+200000=790000\]&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both;&quot;&gt;
&lt;span style=&quot;font-family: &amp;quot;arial&amp;quot; , &amp;quot;helvetica&amp;quot; , sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both;&quot;&gt;
&lt;span style=&quot;font-family: &amp;quot;arial&amp;quot; , &amp;quot;helvetica&amp;quot; , sans-serif;&quot;&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both;&quot;&gt;
&lt;span style=&quot;font-family: &amp;quot;arial&amp;quot; , &amp;quot;helvetica&amp;quot; , sans-serif;&quot;&gt;\[a_{21}=(76000*3)+(63000*5)+(45000*4)=228000+315000+180000=723000\]&lt;/span&gt;&lt;/div&gt;
&lt;div&gt;
&lt;span style=&quot;font-family: &amp;quot;arial&amp;quot; , &amp;quot;helvetica&amp;quot; , sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div&gt;
&lt;span style=&quot;font-family: &amp;quot;arial&amp;quot; , &amp;quot;helvetica&amp;quot; , sans-serif;&quot;&gt;\[a_{31}=(72000*3)+(56000*5)+(38000*4)=216000+280000+152000=648000\]&lt;/span&gt;&lt;/div&gt;
&lt;div&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div&gt;
&lt;span style=&quot;font-family: &amp;quot;arial&amp;quot; , &amp;quot;helvetica&amp;quot; , sans-serif;&quot;&gt;\[AB=\begin{bmatrix} 790000\\ 723000\\ 648000 \end{bmatrix}\]&lt;/span&gt;&lt;/div&gt;
&lt;div&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div&gt;
&lt;span style=&quot;font-family: &amp;quot;arial&amp;quot; , &amp;quot;helvetica&amp;quot; , sans-serif;&quot;&gt;Entonces el costo del viaje para cada una de las opciones de hospedaje es:&lt;/span&gt;&lt;/div&gt;
&lt;div&gt;
&lt;span style=&quot;font-family: &amp;quot;arial&amp;quot; , &amp;quot;helvetica&amp;quot; , sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;

&lt;div class=&quot;separator&quot; style=&quot;clear: both;&quot;&gt;
&lt;span style=&quot;font-family: &amp;quot;arial&amp;quot; , &amp;quot;helvetica&amp;quot; , sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;

&lt;span style=&quot;font-family: &amp;quot;arial&amp;quot; , &amp;quot;helvetica&amp;quot; , sans-serif;&quot;&gt;El problema me pide hallar la noches que programo la agencia en cada ciudad, para ello me sale el siguiente sistema de ecuaciones:&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both;&quot;&gt;
&lt;span style=&quot;font-family: &amp;quot;arial&amp;quot; , &amp;quot;helvetica&amp;quot; , sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both;&quot;&gt;

&lt;div class=&quot;separator&quot; style=&quot;clear: both;&quot;&gt;
&lt;span style=&quot;font-family: &amp;quot;arial&amp;quot; , &amp;quot;helvetica&amp;quot; , sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both;&quot;&gt;
&lt;span style=&quot;font-family: &amp;quot;arial&amp;quot; , &amp;quot;helvetica&amp;quot; , sans-serif;&quot;&gt;Donde X seria el numero de noches en Cartagena, Y el numero de noches en Santa Marta y Z el numero de noches en Barranquilla.&amp;nbsp;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both;&quot;&gt;
&lt;span style=&quot;font-family: &amp;quot;arial&amp;quot; , &amp;quot;helvetica&amp;quot; , sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both;&quot;&gt;
&lt;span style=&quot;font-family: &amp;quot;arial&amp;quot; , &amp;quot;helvetica&amp;quot; , sans-serif;&quot;&gt;Ahora procedemos a realizar la matriz quedando de la siguiente forma:&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both;&quot;&gt;
&lt;span style=&quot;font-family: &amp;quot;arial&amp;quot; , &amp;quot;helvetica&amp;quot; , sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both;&quot;&gt;
&lt;span style=&quot;font-family: &amp;quot;arial&amp;quot; , &amp;quot;helvetica&amp;quot; , sans-serif;&quot;&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both;&quot;&gt;

&lt;div&gt;
&lt;br /&gt;
Ahora se procede a resolver por Gauss Jordan pero primero simplificaremos de la siguiente manera&lt;br /&gt;
&lt;br /&gt;
\[ F1 \div 1000 = F1 \] \[ F2 \div 1000 = F2 \] \[ F3 \div 1000 = F3 \]&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both;&quot;&gt;
&lt;span style=&quot;font-family: &amp;quot;arial&amp;quot; , &amp;quot;helvetica&amp;quot; , sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both;&quot;&gt;
&lt;span style=&quot;font-family: &amp;quot;arial&amp;quot; , &amp;quot;helvetica&amp;quot; , sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both;&quot;&gt;
&lt;span style=&quot;font-family: &amp;quot;arial&amp;quot; , &amp;quot;helvetica&amp;quot; , sans-serif;&quot;&gt;La matriz me queda de la siguiente manera:&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both;&quot;&gt;
&lt;span style=&quot;font-family: &amp;quot;arial&amp;quot; , &amp;quot;helvetica&amp;quot; , sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both;&quot;&gt;
&lt;span style=&quot;font-family: &amp;quot;arial&amp;quot; , &amp;quot;helvetica&amp;quot; , sans-serif;&quot;&gt;\[\left [ \left.\begin{matrix} 80 &amp;amp; 70 &amp;amp; 50 \\ 76 &amp;amp; 63 &amp;amp; 45 \\ 72 &amp;amp; 56 &amp;amp; 38 \end{matrix}\right|\begin{matrix} 540 \\ 494 \\ 444 \end{matrix} \right ]\]&lt;/span&gt;&lt;/div&gt;

&lt;div class=&quot;separator&quot; style=&quot;clear: both;&quot;&gt;
&lt;span style=&quot;font-family: &amp;quot;arial&amp;quot; , &amp;quot;helvetica&amp;quot; , sans-serif;&quot;&gt;Ahora empezamos a utilizar el método de Gauss Jordan para resolver el sistema.&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both;&quot;&gt;
&lt;b&gt;Primero: Convertimos la posición 21(2 fila, 1 columna) en 0&lt;/b&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both;&quot;&gt;
Utilizamos la siguiente operación &amp;nbsp;\[((-76)*F1)+(80*F2)=&amp;gt; F2\]&amp;nbsp;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;

\[\begin{matrix} -6080 &amp;amp; -5320 &amp;amp; -3800 &amp;amp; -41040\\ +6080 &amp;amp; +5040 &amp;amp; +3600 &amp;amp; +39520\\ --- &amp;amp; --- &amp;amp; --- &amp;amp; ---\\ 0 &amp;amp; -280 &amp;amp; -200 &amp;amp; -1520 \\ \end{matrix}\]&amp;nbsp;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both;&quot;&gt;
Ahora simplificamos: \[\begin{matrix} 0 &amp;amp; 7 &amp;amp; 5 &amp;amp; 38 \end{matrix} =&amp;gt; F2\]&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both;&quot;&gt;
La Matriz me queda de la siguiente forma: \[\left [ \left.\begin{matrix} 80 &amp;amp; 70 &amp;amp; 50 \\ 0 &amp;amp; 7 &amp;amp; 5 \\ 72 &amp;amp; 56 &amp;amp; 38 \end{matrix}\right|\begin{matrix} 540 \\ 38 \\ 444 \end{matrix} \right ]\]&amp;nbsp;&lt;/div&gt;

&lt;br /&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both;&quot;&gt;
&lt;b&gt;Segundo: Convertimos la posición 31(3 fila, 1 columna) en 0&lt;/b&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both;&quot;&gt;
&lt;b&gt;&lt;br /&gt;&lt;/b&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both;&quot;&gt;
Utilizamos la siguiente operación \[((-72)*F1)+(80*F3)=&amp;gt; F3\]&lt;/div&gt;
&lt;div&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div&gt;
\[\begin{matrix} -5760 &amp;amp; -5040 &amp;amp; -3600 &amp;amp; -38880\\ +5760 &amp;amp; +4480 &amp;amp; +3040 &amp;amp; +35520\\ --- &amp;amp; --- &amp;amp; --- &amp;amp; ---\\ 0 &amp;amp; -560 &amp;amp; -560 &amp;amp; -3360 \\ \end{matrix}\]&lt;/div&gt;
&lt;div&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div&gt;
Ahora simplificamos: \[\begin{matrix} 0 &amp;amp; 1 &amp;amp; 1 &amp;amp; 6 \end{matrix} =&amp;gt; F3\]&lt;/div&gt;
&lt;div&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div&gt;
La matriz queda de la siguiente forma:&amp;nbsp;\[\left [ \left.\begin{matrix} 80 &amp;amp; 70 &amp;amp; 50 \\ 0 &amp;amp; 7 &amp;amp; 5 \\ 0 &amp;amp; 1 &amp;amp; 1 \end{matrix}\right|\begin{matrix} 540 \\ 38 \\ 6 \end{matrix} \right ]\]&lt;/div&gt;
&lt;div&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div&gt;
&lt;b&gt;Tercero: Convertimos la posición 32(3 fila, 2 columna) en 0&lt;/b&gt;&lt;/div&gt;
&lt;div&gt;
&lt;b&gt;&lt;br /&gt;&lt;/b&gt;
Utilizamos la siguiente operación \[((-1)*F2)+(7*F3)=&amp;gt; F3\]&lt;/div&gt;
&lt;div&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div&gt;
\[\begin{matrix} 0 &amp;amp; -7 &amp;amp; -5 &amp;amp; -38\\ 0 &amp;amp; +7 &amp;amp; +7 &amp;amp; +42\\ --- &amp;amp; --- &amp;amp; --- &amp;amp; ---\\ 0 &amp;amp; 0 &amp;amp; 2 &amp;amp; 4 \\ \end{matrix}\]&lt;/div&gt;
&lt;div&gt;
&lt;b&gt;&lt;br /&gt;&lt;/b&gt;&lt;/div&gt;
&lt;div&gt;
Ahora simplificamos:&amp;nbsp;\[\begin{matrix} 0 &amp;amp; 0 &amp;amp; 1 &amp;amp; 2 \end{matrix} =&amp;gt; F3\]&amp;nbsp;&lt;/div&gt;
&lt;div&gt;
&lt;b&gt;&lt;br /&gt;&lt;/b&gt;
La matriz queda de la siguiente forma:&amp;nbsp;\[\left [ \left.\begin{matrix} 80 &amp;amp; 70 &amp;amp; 50 \\ 0 &amp;amp; 7 &amp;amp; 5 \\ 0 &amp;amp; 0 &amp;amp; 1 \end{matrix}\right|\begin{matrix} 540 \\ 38 \\ 2 \end{matrix} \right ]\]&lt;/div&gt;

&lt;br /&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both;&quot;&gt;
&lt;b&gt;Cuarto: Convertimos la posición 23(2 fila, 3 columna) en 0&lt;/b&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both;&quot;&gt;
&lt;b&gt;&lt;br /&gt;&lt;/b&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both;&quot;&gt;
Utilizamos la siguiente operación: \[F2+((-5)*F3)=&amp;gt;F2\]&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;

&lt;br /&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both;&quot;&gt;
Ahora simplificamos:&amp;nbsp;\[\begin{matrix} 0 &amp;amp; 1 &amp;amp; 0 &amp;amp; 4 \end{matrix} =&amp;gt; F2\]&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both;&quot;&gt;

&lt;div class=&quot;separator&quot; style=&quot;clear: both;&quot;&gt;
La matriz queda de la siguiente forma: \[\left [ \left.\begin{matrix} 80 &amp;amp; 70 &amp;amp; 50 \\ 0 &amp;amp; 1 &amp;amp; 0 \\ 0 &amp;amp; 0 &amp;amp; 1 \end{matrix}\right|\begin{matrix} 540 \\ 4 \\ 2 \end{matrix} \right ]\]&lt;/div&gt;
&lt;div&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both;&quot;&gt;
&lt;b&gt;Quinto: Convertimos la posición 13(1 fila, 3 columna) en 0&lt;/b&gt;&lt;/div&gt;
&lt;/div&gt;
&lt;div&gt;
&lt;b&gt;&lt;br /&gt;&lt;/b&gt;&lt;/div&gt;
&lt;div&gt;
Utilizamos la siguiente operación: \[F1+((-50)*F3)=&amp;gt;F1\]&lt;/div&gt;
&lt;div&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div&gt;
\[\begin{matrix} 80 &amp;amp; 70 &amp;amp; 50 &amp;amp; 540\\ 0 &amp;amp; 0 &amp;amp; -50 &amp;amp; -100\\ --- &amp;amp; --- &amp;amp; --- &amp;amp; ---\\ 80 &amp;amp; 70 &amp;amp; 0 &amp;amp; 440 \\ \end{matrix}\]&lt;/div&gt;
&lt;div&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div&gt;
Ahora simplificamos:&amp;nbsp;\[\begin{matrix} 8 &amp;amp; 7 &amp;amp; 0 &amp;amp; 44 \end{matrix} =&amp;gt; F1\]&lt;/div&gt;
&lt;div&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div&gt;
La matriz queda de la siguiente forma: \[\left [ \left.\begin{matrix} 8 &amp;amp; 7 &amp;amp; 0 \\ 0 &amp;amp; 1 &amp;amp; 0 \\ 0 &amp;amp; 0 &amp;amp; 1 \end{matrix}\right|\begin{matrix} 44 \\ 4 \\ 2 \end{matrix} \right ]\]&lt;/div&gt;
&lt;div&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div&gt;
&lt;b&gt;Sexto: Convertimos la posición 12(1 fila, 2 columna) en 0&lt;/b&gt;&lt;/div&gt;
&lt;div&gt;
&lt;b&gt;&lt;br /&gt;&lt;/b&gt;&lt;/div&gt;
&lt;div&gt;
Utilizamos la siguiente operación:&amp;nbsp;\[F1+((-7)*F2)=&amp;gt;F1\]&lt;br /&gt;
&lt;br /&gt;
\[\begin{matrix} 8 &amp;amp; 7 &amp;amp; 0 &amp;amp; 44\\ 0 &amp;amp; -7 &amp;amp; 0 &amp;amp; -28\\ --- &amp;amp; --- &amp;amp; --- &amp;amp; ---\\ 8 &amp;amp; 0 &amp;amp; 0 &amp;amp; 16 \\ \end{matrix}\]&lt;/div&gt;
&lt;div&gt;
&lt;br /&gt;
Ahora simplificamos:&amp;nbsp;\[\begin{matrix} 1 &amp;amp; 0 &amp;amp; 0 &amp;amp; 2 \end{matrix} =&amp;gt; F1\]&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both;&quot;&gt;
&lt;span style=&quot;font-family: &amp;quot;arial&amp;quot; , &amp;quot;helvetica&amp;quot; , sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both;&quot;&gt;
&lt;span style=&quot;font-family: &amp;quot;arial&amp;quot; , &amp;quot;helvetica&amp;quot; , sans-serif;&quot;&gt;&lt;span style=&quot;font-family: &amp;quot;times new roman&amp;quot;;&quot;&gt;La matriz queda de la siguiente forma:&amp;nbsp;&lt;/span&gt;&lt;/span&gt;\[\left [ \left.\begin{matrix} 1 &amp;amp; 0 &amp;amp; 0 \\ 0 &amp;amp; 1 &amp;amp; 0 \\ 0 &amp;amp; 0 &amp;amp; 1 \end{matrix}\right|\begin{matrix} 2 \\ 4 \\ 2 \end{matrix} \right ]\]&lt;/div&gt;
&lt;div&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div&gt;
Ya tenemos resuelta el sistema por lo tanto el resultado es el siguiente:&lt;br /&gt;
\[\begin{matrix} 1 &amp;amp; 0 &amp;amp; 0 &amp;amp; 2 \end{matrix} =&amp;gt; F1\] &lt;br /&gt;
&lt;br /&gt;
\[x=2= 2 \ noches \ en \ Cartagena\]&lt;br /&gt;
\[y=4= 4 \ noches \ en \ Santa \ Marta\]&lt;br /&gt;
\[z=2= 2 \ noches \ en \ Barranquilla\]&lt;/div&gt;
&lt;div&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both;&quot;&gt;
&lt;span style=&quot;font-family: &amp;quot;arial&amp;quot; , &amp;quot;helvetica&amp;quot; , sans-serif;&quot;&gt;&lt;span style=&quot;font-family: &amp;quot;times new roman&amp;quot;;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both;&quot;&gt;
