Mr Woods
Solve each equation using the “elimination” method (make sure to show all work and perform a
check!):
11)
3x – 4y = - 6
2x + 4y = 16
12)
3x + 2y = 23
x = -3y + 3

Mr Woods
Solve each equation using the “substitution” method (make sure to show all work and perform a
check!):
13)
4x – y = 9
x – 3y = 16
14) 3x - y = 6
- 6x + y = - 12
