Lesson Summary:

In this lesson, you will learn how to solve a literal equation with one rational expression. The key to solving a problem with a rational term is to recognize that the inverse operation is to multiply, not divide like with a regular variable. By adding or subtracting variables and then multiplying by the rational denominator, you can solve for the desired variable. With this method, you can easily solve complex literal equations with rational expressions.

Lesson Description:

Solving a literal equation with one rational expression

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.
