What is the solution to the system of equations, y=2x+6 and 3x-y=6?

OpenStudy (blurbendy):

you know y = 2x + 6, so you can substitute it into the other equation 3x - 6 = y 3x - 6 = 2x + 6 solve for x

OpenStudy (blurbendy):

then substitute x into the first equation

OpenStudy (anonymous):

Would x=1 then?

OpenStudy (anonymous):

Oh so the solution is (7,20)?
