This document contains a math lesson on solving systems of linear equations using elimination. It includes 4 practice problems for students to solve, as well as instructions for students to work on an exit slip problem with a partner and complete homework problems from their textbook. The document provides scaffolding and examples to help students master the skill of eliminating variables when solving systems of linear equations.

1. Opener: Fill in your name and ID on your math raffle tickets.
Solve these systems using elimination.
1. 5x + 3y = 12
‐3y ‐ 2x = ‐3
2. 7x ‐ 2y = 26
‐2x ‐ 2y = ‐10
