Youtube videos by Julie Harland are organized at http://YourMathGal.com. This video shows how to solve a system of 3 three linear equations in 3 variables using the substitution method, and also partly the addition (elimination) method to solve a system of 2 equations. The same problem is solved in System of Equations 3 variables - 1 using the Addition Method. Aligned to CCSS: HSA-REI.6 .For more great math videos visit: www.youtube.com/user/videosbyjulieharland/videos
