Amsco Integrated Algebra I: Solving for a Variable in Terms of Another Variable
 This is a free lesson from our course in Amsco's Integrated Algebra

 This lesson explains how to solve equations if it contains more than one variable. Such equation can be solved by expressing one variable in terms of another one. E.g. the equation ax + b = 3b contains the variables a, b, and x. Given to solve this equation for x means, express x in terms of the other variables using the following operations/procedure: Step 1. Write the equation ax +b= 3b Step 2. Subtract b from each side ax+b-b=3b-b, it gives ax=2b Step 3. Divide both sides by a, it yields ax/a=2b/a Step 4. Simplify each side, you get the answer x=2b/a. The video below will explain in detail with the help of several examples.

 As many of you know, Winpossible's online courses use a unique teaching method where an instructor explains the concepts in any given area to you in his/her own voice and handwriting, just like you see your teacher explain things to you on a blackboard in your classroom. This particular lesson includes the teacher's instruction, practice questions as well as end-of-lesson quizzes for practice. As we mentioned above, you can enroll in our online course in Trigonometry by clicking here. The format of Winpossible's online courses is also very suitable for teachers who are using an interactive whiteboard such as Smartboard on Promethean in their classrooms, because the course lessons can be easily displayed on such interactive whiteboards. Volume pricing is available for schools interested in our online courses. For more information, please contact us at educators@winpossible.com.
