Solve the system by the substitution method. x-3y=-3 3x-2y=-2

OpenStudy (jdoe0001):

hmm can you solve the 1st for "y"?

OpenStudy (anonymous):

No, this is my first time doing this kind of math.

OpenStudy (jdoe0001):

well.ok.... so.. how about if you say subtract "x" from both sides and then divide by sides by " -3 " what do you end up with?

OpenStudy (tkhunny):

Why are we solving for y? x = 3y - 3 Solving the first for x seems awfully straight-forward.
