Lesson Summary:

In this lesson, the instructor teaches how to solve multi-step equations that involve fractions by clearing the fractions. To get rid of the fractions, multiply each side of the equation by the least common multiple of the denominators. By doing so, we can eliminate fractions and make it easier to combine like terms. The lesson also includes an example of an equation with no solution and shows how to identify such equations.

Lesson Description:

Solving a multi-step equation by multiplying by the denominator

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.

    This lesson shows how you can get rid of fractions in a multi-step equation by multiplying. It also gets a little bit into what an equation that has no solutions looks like.
