Lesson Summary:

In this lesson, we learn how to solve a one step equation by subtracting with a double negative. We are reminded that two negative signs next to each other cancel each other out and can be rewritten as a positive. Using inverse operations, we undo what is happening to the variable and solve for x. By subtracting 74 from both sides, we are left with x equaling negative 96. This lesson provides a clear and simple explanation for solving one step equations with subtraction.

Lesson Description:

Solving a one step equation by subtracting with a double negative

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.
