In this lesson, you will learn how to solve a one-step equation using the addition property of equality. The first step is to circle the variable, which is the value you're solving for. Then, figure out what operation is happening to the variable, which in this case is subtraction. Use the inverse or opposite operation, which is addition in this example, to get the variable alone on one side of the equation. Finally, check your answer by plugging it back into the original equation. With these steps, you'll be able to solve one-step equations with ease.
How to solve an equation using the addition 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.
