Jeremy helps Madeline build a rectangular pen with a perimeter of 86 feet. Twice the pen's width is one more than three times its length. What is the width of the pen?
-------------
Perim = 2(width + length)
Perim = 2*width + 2*length
---
2W = 3L + 1
--------
86 = 3L+1 + 2L
----
86 = 5L + 1
5L = 85
Length = 17 feet
-----
Solve for "W":
2W = 3L + 1
2W = 51+1
Width = 26 feet
