Solving One-Step Equation by Subtracting
This lesson teaches how to solve one-step equations using the subtraction property of equality. The first step is to circle the variable and identify the operation being added or subtracted to it. The next step is to use the inverse operation, in this case, subtraction, to isolate the variable. By subtracting the same number from both sides of the equation, the variable becomes isolated and the solution can be found. This method can be used for any one-step equation involving addition or subtraction.
How to solve a one step equation using the subtraction property of equality
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 to solve a very basic one-step equation by using the subtraction property of equality. The idea of getting the variable by itself is discussed and explained along with using subtraction to solve.
