Solve a system by substitution: one equation solved for y

Use substitution or elimination so that you find x and y. Write your answer as (x, y).

1. Solve the system: y = 3x + 12 and x + 3y = −14. Write your answer as (x, y).
2. Solve the system: y = −x − 1 and x − 3y = 11. Write your answer as (x, y).
3. Solve the system: y = −x − 9 and x + 2y = −15. Write your answer as (x, y).
4. Solve the system: y = 3x + 6 and 2x − y = −2. Write your answer as (x, y).
5. Solve the system: y = −x − 8 and x + 2y = −9. Write your answer as (x, y).
6. Solve the system: y = 5x − 10 and x + y = −4. Write your answer as (x, y).
7. Solve the system: y = −3x − 27 and 3x + 2y = −33. Write your answer as (x, y).
8. Solve the system: y = 6x − 43 and 2x − y = 19. Write your answer as (x, y).
9. Solve the system: y = 6x + 26 and x − 3y = 7. Write your answer as (x, y).
