2x=x+6, x=6, y=6+6, y=12, (6,12)
OpenStudy (anonymous):
there you go, (6,12)
OpenStudy (anonymous):

OpenStudy (anonymous):
well, you have to substitute either one, like you can substitute y to 2x, then after you get 2x=x+6, you subtract the x and get x=6, from there substitute to the second the x and you get y=12
