Tue, 18 Aug 2009 05:09:26 -0700

Part 2 of 2. [NOTE: This video is only the first 20 minutes of the full lesson. Purchase or rent to view entire video]

This lesson consists of providing you with a Self-Tutorial on how to solve typical linear word problems (story problems or applied problems). I will show you how to solve for a specific variable in formulas. I also discuss how to covert a repeating decimal into a fraction (which was skipped in Basic Math: Lesson 6 -"Fractions") and will teach you how to convert units of measurement.

Examples of word problems done include:

Finding a number based on certain criteria.
Word problems involving some geometry (triangle, rectangle, circle).
Age problems.
Mixture problems.
Money problems (story of my life!).
Rate-Time-Distance problems.
Percent Equations/problems.
Ratio and Proportion (concepts and solving problems, including similar triangles).
Problems dealing with Unit Price.

Algebra: Solving Linear Equations - Part 1: The Basics

Tue, 18 Aug 2009 05:02:03 -0700

Part 1 of 2. Lesson consists of providing you with a Self-Tutorial on how to solve linear equations. Tutor discusses what is an Equation, Solution, Solution Set, Equivalent Equations, Identity, Contradictions, Conditional Equations, Linear Equations, the Standard Form of a Linear Equation. I show you how to actually SOLVE linear equations going step-by-step. I don't skip steps. I review some of the properties of Equality here too. I remind you to check the work done and how to solve linear equations using a calculator. At the end, you will know how to easily solve equations that look like:

2[y - (4y - 1)] = 5 - 9y

No word problems are done here. This is shown in DETAIL in Part 2 of the Lesson.
