The perimeter of a rectangle is 34 inches. The length is 4 less than twice the width. What is the length of the rectangle? Write a system of equations for the problem. Which one of the equations below would be part of that system?

2L+2W=4
2L+2W=30
L=2W-4
L=4W-2

Hopefully, we would start with 2L + 2W = 34
You find the other one that expresses "The length is 4 less than twice the width."
