About This Lesson
http://www.freemathvideos.com In this video series I show you how to solve a system of equations using elimination. When using elimination we need to make sure that coefficients of the same variable are equal in absolute value. If they have the same sign then we subtract the equations. If they have opposite signs then we add the equations. If the variables do not have the same absolute value coefficients then we need to multiply one or both equations by a multiple to achieve this result. When combining the two equations we will eliminate a variable and then solve for the other. We then plug back the value of one variable into one of the original equations to find the value of the other variable.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 exaclty 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: Blogger: www.mrbrianmclogan.blogspot.comTwitter: @mrbrianmcloganFacebook: mrbrianmclogan
