Use the substitution method to solve the system. x + 7y = 7 2x - 3y = -3 Type your answer as an ordered pair. (x,y)
First thing ya wanna do is solve for a variable so x = 7 - 7y |dw:1334254783676:dw| Then plug it into the other equation (substituting) like so |dw:1334254853696:dw| So y = 1 And then you plug y back in to find x :D
