In this lesson on two-step equations, we learn to use inverse operations to undo addition and subtraction before undoing multiplication or division. To solve the equation, we circle the variable to indicate that it is pinned, and then use inverse operations to undo each step of the equation. Ultimately, we arrive at the solution by isolating the variable and performing the necessary arithmetic. Remembering these steps will allow us to easily solve any two-step equation presented to us.
Solving a two step equation
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.
