x = -1

y = 3

Step-by-step explanation:

Add the two equations together.

You get:

4x = -4

You may notice that there is no y, and that is because the y's cancel out. -y + y = 0, so there's no use in putting y in.

x = -1.

Plugging x in, we get:

-1 - 2y = -7.

Move the -7 over to the left side.

6 = 2y

Therefore, y = 3.

We can check our answer by plugging the values in.

3(-1) + 2(3) is supposed to equal 3.

-3 + 6 = 3, and so we know our answer is correct.
