Directions: For problems 5 – 8, solve each system using the elimination method. 6. 4x + 3y = –2 and 4x + 5y = 14
7. –x + 3y = –1 and x – 2y = 2
1
8. x + 2y = 10 and 3x – y = 9
9. 4x + 3y = –6 and 5x – 2y = –19
Directions: Solve each system using either substitution or elimination. 10. y = 2x – 5 and y = 3 + x
11. 5x + 2y = 10 and 4x + y = 4
2
12. x + y = 10 and x – y = 2
