Answer:

(1, 4)

Step-by-step explanation:

5x-2y=-3 -2x-y=-6 =>

5x-2y=-3

-2x-y=-6 Multiply all three terms by -2: 4x + 2y = 12

Then we have:

5x-2y=-3

4x + 2y = 12

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

9x = 9 and so x = 1. Then, using -2x - y = -6, and substituting 1 for x:

-2(1) - y = -6, or

2 + y = 6, or

y = 4

Then the solution is (1, 4)
