Answer 2

Did you want to solve for x and y then?

Answer 3

Assuming that you do, you want to multiply the bottom equation by 4, getting 20y = -12 + 40x, then you subtract 15x on both sides of the first one, getting -20y = 7-15x:

After that you add both equations and solve for x, then plug x back in and solve for y

x=1/11
y=-31/110
