Solve 

Actually, someone has already presented the second variable, y, as y=5x-13.

Substitute (5x+13) for y in the second equation.

Please show your work.

Be an opportunist.  Go the easiest way that is still valid.  If you already have one equation in which a formula for y is presented, substitute this formula (5x+13) into the second equation.  There's no rule that says you have to find the first variable first or the second variable first; choose the easiest valid approach.
