Solving Systems with Elimination
Date________________ Period____
Solve each system by elimination.
1) -9x + 8 y = -8
2x - 8 y = 8
2) 3x + 2 y = 2
-3x - 8 y = 28
3) x + 6 y = -1
2x - 6 y = -20
4) 4x + 10 y = -26
-9x - 10 y = 21
5) 6x + y = -14
-x - y = -1
6) x - 6 y = 18
5x + 6 y = 18
7) -6x - y = 15
4x + y = -7
8) -x + 5 y = 26
x + 3 y = 30
