Answer 1

Do you know how to use substitution?

Answer 2

Sorry about the site going down :/
if you come back...
y = y
so 2x+2 = -2x-1 solve for x
add 2x to both sides
subtract 2 from both sides
divide both sides by 4
that should get you x :)

once you get x
plug it into y = 2x + 2 and solve for y ^_^
