Elimination method review (systems of linear equations)
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.
Systems of equations with elimination - Khan Academy
Solve systems of equation with one-step elimination (e.g., x-values or y-values cancel each other out).
Systems of equations with elimination (and manipulation)
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.

Solving systems of linear equations | Lesson - Khan Academy
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 …
Systems of equations with elimination
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 …
Systems of equations with elimination: x-4y=-18 & -x+3y=11
Basically, you manipulate the equations (multiplying both sides by a number, for instance) to cancel out one of the variables, leaving only 1 left, thus allowing you to solve for the variable left.
