A Small Change: Suppose that the length L of a certain rectangle is k meters less than m times its width w. The perimeter of the rectangle is p meters. Find the length and width of the rectangle.

p might or might not be an even number.
CONSTANTS: m, k, p
UNKNOWNS: L and w
and

using substitution;

-
Rearrange the L equation, mw=L+k, w=(L+k)/m.
-
Substitute w into the perimeter equation:
