In this video, you will learn how to solve a system of equations using elimination. By adding or subtracting the equations, you can eliminate one variable and solve for the other. The speaker shows an example of this by multiplying one of the equations by two to eliminate the x variable. However, if you end up with a zero equals a non-zero number, there is no solution, meaning the lines are parallel. This lesson provides a clear explanation of how to use elimination to solve a system of equations.

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.
