Answer:

the solution is (-3, 0)

Step-by-step explanation:

Find the solution using elimination by adding/subtracting:

5x + 2y = -15

2x - 2y = -6

----------------------

7x         = -21         and so x = -3.

Substituting -3 for x in 2x - 2y = -6, we get:

2(-3) - 2y = -6, or

-2y = 0

Then y must be 0, and the solution is (-3, 0)
