The width of a rectangle is x inches long. The length of that rectangle is 5 inches less than Twice the width. If the perimeter measures 26 inches, what is the measure of the length and width of the rectangle. Show all the work and the algebra you used to solve this problem.

If width = x, then 2x5 = length.
2x + 2(2x5) = 26
Solve for x.
