Hello!! Actually I got A x = 2, y = 12.

Whenever you plug them in, 2(2) + 3(12) = 40

-2(2) + 2(12) = 20

It worked for me this way, I hope this is the right answer. Have a great day!

2x + 3y = 40

-2x + 2y = 20

------------------------add

5y = 60

y = 12

-2x + 2y = 20

-2x +2(12) = 20

-2x + 24 = 20

-2x = -4

x = 2

answer is A. x = 2, y = 12
