The Elimination Method

Date________________ Period____

Solve each system by elimination.

1) -3x + 6 y = -18 2x - 6y = 16

2) x - y = -8 -x - 2y = -4

3) 3x + 6 y = 30 -6x - 2 y = 10

4) -7x - 8 y = -18 14x + 7 y = 0

5) 9x - 6 y = 24 10x + 12 y = 8

6) -x - 3 y = 11 4x - y = 8

7) 2x + 4 y = -4 8x + 5y = 17

8) -4x + y = 3 -8x + 2y = 6

3 9) -4 = - y - x

2

-26 = -7 y - 10x

10) -2 y + 1 = 9x 0 = 15 - 5y - 10x
