Solve by substitution.
1. y = x + 1 2. x + y = -4 3. x – 2y = 7
x + y = 9 2x + y = 5 2x + 3y = 7
4. 3x + y = 3 5. 2x + 4y = 6 6. 3x -2y = 5
-x – y = 4 x + 2y = 3 x + 4y = 4
Solve by elimination.
7. x – y = 5 8. 5m – n = 9 9. -3x + 2y =-1
3x +y = 7 6m – n = 13 5x – y = 4
10. 8x + 3y = 9 11. 2x + 5y = 19 12. 6x – 5y = 19
5x + 6y = -15 -3x + 4y = -17 5x + 4y = -25
