Lesson Summary:

This lesson teaches you how to solve one-step inequalities using multiplication. The instructor reminds us that to undo multiplication, we need to divide, but instead of dividing fractions, we can multiply by the reciprocal. He demonstrates how to multiply by the reciprocal on both sides, and how to properly scale and test our point on a number line. By following these steps, we can solve simple one-step inequalities quickly and easily.

Lesson Description:

Solving a simple one step inequality using multiplication

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.
