Lesson Summary:

In this lesson, the instructor shows how to solve an equation for x and solve for y. To solve for x, you need to undo everything that is happening to x. Then you need to isolate x on one side of the equation. To solve for y, you need to get y alone on one side of the equation. You do this by undoing everything that is happening to y, then isolating y on one side of the equation.

Lesson Description:

Solving an equation for x and then solving for y

I show how to solve math problems online during live instruction in class. This is my way of providing free tutoring for the students in my class and for students anywhere in the world. Every video is a short clip that shows exactly how to solve math problems step by step. The problems are done in real time and in front of a regular classroom. These videos are intended to help you learn how to solve math problems, review how to solve a math problems, study for a test, or finish your homework. I post all of my videos on YouTube, but if you are looking for other ways to interact with me and my videos you can follow me on the following pages through My Blog, Twitter, or Facebook.
