▹ Answer
<em>(-2, 1)</em>
▹ Step-by-Step Explanation
4x + 3y = -5
-2x + 2y = 6
4x + 3y = -5
x = -3 + y
4(-3 + y) + 3y = -5
y = 1
x = -3 + 1
x = -2
(x, y) = (-2, 1)

The perimeter of a rectangle is 2 times the length and 2 times the width. Since you got the perimeter (240), you can multiply 2 by the length (160) and subtract the perimeter (240) by it, giving you 80. This is 2 times the width. Divide that by 2 (divide 80 by 2) and you will get 40. The width is 40 feet.
