Answer:

A. (-4, 8)

Explanation:

3x+2y=4

-2x+2y=24

Add 2x on both sides

2y=2x+24

divide both sides by 2

y=x+12

Substitute the new equation into one of the two equations.

3x+2(x+12)=4

3x+2x+24=4

Subtract 24 on both sides and add 3x and 2x together

5x=-20

Divide 5 on both sides and you get -4

Now substitute -4 for x in one of the equations the question is asking of

-2(-4)+2y=24

8+2y=24

Substract 8 on both sides

2y/2= 16/2

y= 8

So your final answer is (-4,8).

Hope this helps.
