Title: Systems of Linear Equations – Elimination (Addition) Method
... (addition) method, along with analyzing the solution. Recall that a system of equations consists of two or more equations each with two or more variables. A solution to a system in two variables is an ordered pair (x , y ) that satisfies each equation in the system. For now, we will concentrate on s ...

Solving Systems of Equations by Elimination with Multiplication
... Multiply the first equation by –2 so the coefficients of the y terms are additive inverses. Then add the equations. 2x + y = 23 ...
