It would take just over 6 minutes assuming it takes him 2. 6 minutes to wax a single square inch somehow.
If we add the equations it looks like
-5y + 8x + 5y + 2x = -18+58
so 10x=40
so x=40/10=4
now let's replace x by 4 in the second equation
5y +2*4=58
5y=58-2*4=58-8=50
so y=50/5=10
so (x, y) = (2, 10)
That's answer exactly is -5
