The plans for a rectangular deck call for the width to be 6 feet less than the length. Sam wants the deck to have an overall perimeter of 56 feet. What should the length of the deck be?

Two equations:  
W= L-6
2W + 2L = 56 (perimeter is just all four sides added together).

Substitute the W value in equation one into W in equation two-solve for L:  that will give you value of L which is being asked for.
