Solving Systems by Elimination

Unit 9: Systems of Equations
Lesson 18 of 20

Objective: SWBAT apply the idea that, given a system of two equations in two variables, replacing one equation by the sum of that equation and a multiple of the other produces a system with the same solution.

Big Idea: The purpose of yesterday's lesson was to build appreciation for the idea behind elimination. Now it's time to apply that idea and solve some systems!
