The elimination method is a technique for solving systems of linear equations. This article reviews the technique with examples and even gives you a chance to try the method yourself.

In some cases, we need to slightly manipulate a system of equations before we can solve it using the elimination method. See how it's done in this video.

Look at two ways to solve systems of linear equations algebraically: substitution and elimination. Look at systems of linear equations graphically to help us understand when systems of linear equations have …

Walk through examples of solving systems of equations with elimination. In this article, we're going to be solving systems of linear equations using a strategy called elimination. First, we need to understand …

To "scale up," one would simply multiply both sides of the equation by a value. The reason why one would scale up is to rewrite the equation so that a variable term will eliminate when it is added to …

I figure it never hurts getting as much practice as possible solving systems of linear equations, so let's solve this one. What I'm going to do is I'm going to solve it using an augmented matrix, and I'm going …

Sal solves a linear system with 3 equations and 4 variables by representing it with an augmented matrix and bringing the matrix to reduced row-echelon form.
