Answer:

The solution set would be (-4, 3)

Step-by-step explanation:

To find this, we need to multiply the second equation by 4. Then we can add through.

3x - 4y = -24

4x + 4y = -4

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

7x = -28

x = -4

Now that we have the value of x, we can solve for y.

x + y = -1

-4 + y = -1

y = 3
