The perimeter of a rectangle is 48 cm. The length is 6 cm less than twice the width. Which system would model this situation, and what are the length and the width?

Let x=length and y=width

Solve the 2nd equation for x or y (whichever is more convenient) and then plug into the 1st equation.

Substitute y into a previous equation to solve for x.

The length is 14cm and the width is 10cm.
