Answer:

The ordered pair would be (-2, 1)

Step-by-step explanation:

To solve and get an ordered pair, we need to get a term to cancel. We can do this by multiplying the entire second equation by 2

4x + 3y = -5

-4x + 4y = 12

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

7y = 7

y = 1

Now that we have the value of y, we can use it to find x.

-2x + 2y = 6

-2x + 2(1) = 6

-2x + 2 = 6

-2x = 4

x = -2
