Lesson Summary:

In this lesson, you'll learn how to solve and graph an inequality with variables on both sides. The first step is to get the variable on the same side, then rewrite the answer so that the variable is in front. After selecting two points to plug into the inequality, you can determine which side of the line to shade. Finally, test the final point to determine whether to fill in or leave open the circle at the end of the line.

Lesson Description:

Solving and graphing an inequality with variables 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.
