Let "W" be the width of the rectangle.
Let "L" be the length of the rectangle.
Let "P" be the perimeter of the rectangle.
L = 2W - 3
P = 2L + 2W
18 = 2L + 2W
Substitute the value of the length in the equation.
18 = 2(2W - 3) + 2W
18 = 4W - 6 + 2W
24 = 6W
W = 4
The width of the rectangle is 4 inches.
