Solve by solution

Today's assignment, was to Solve by solution, it was an easy process to learn for me. I did this last year, and its kind of not so clear right now but i know with enough practice, i'll be able to do it.

example:

l1; 2x+4y=8
l2; 3x+y= -13

Y would eaqual 8-2x
because you would have to take 2x away from the left side and subtract it on the right side.
