Lesson Summary:

This lesson teaches how to solve an equation with a variable on both sides. The goal is to get the variable by itself, and the best way to do that is to combine the variables by adding or subtracting one of them. It is important to remember the rules of equality - whatever is done to one side of the equation must also be done to the other side. There are different ways to solve these types of problems, but the end goal is always to get the variable by itself.

Lesson Description:

Solving an equation when you have a variable on both sides

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.
