Let w be the width of the rectangle and y be the length,
then y = 5w - 26.  Another equation given is that w times y = 63
The trick is to set this up with two variables and two equations, solve using any method that you know : graphing, substitution, or elimination (also called linear combinations). Maybe you can also see the answer in the two equations?
