Question

I suck at math help please

Answer 1

y=4

Explanation:

If you multiply the first one by 2, you get:

8x - 2y = 56

If you add that one to the second one, the -2y term disappears:

8x+3x-2y+2y = 56+32

11x = 88

x=8 (divide by 11)

Fill in x=8 in the first:

4*8 - y = 28

32 - y = 28

y = 32-28 = 4
