Errors in this video:

At about the 1:22 mark, the teacher says adding a -4 is the exact same thing as subtracting a -4; he should have said adding a -4 is the same thing as subtracting a positive 4.

At about the 1:29 mark, the teacher says that 3+-4 is the same thing as x-4; he should have either said 3+-4 is the same as 3-4 or x+-4 is the same as x-4.

Lesson Summary:

In this lesson, we learn how to solve a two step equation with a rational term by using the reverse order of operations. It's important to pay attention to the sign being added, as adding a negative number is the same as subtracting. By adding or subtracting to obtain zero and multiplying by the inverse operation, we can solve for x. Showing our work and using the inverse operation is crucial to avoid making mistakes.

Lesson Description:

Solving a two step equation with a rational term

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.
