Question
What is the measure of the length of a rectangle with a width of 3x + 4y + 1 and a perimeter of 24x + 18y + 32?

p = 2*width + 2*length
24x + 18y + 32 = 2(3x + 4y + 1) + 2*length
24x + 18y + 32 = 6x + 8y + 2 + 2*length
18x + 10y + 30 = 2*length
9x + 5y + 15 = length
24x + 18y + 32 = 2(3x + 4y + 1) + 2*length
24x + 18y + 32 = 6x + 8y + 2 + 2*length
18x + 10y + 30 = 2*length
9x + 5y + 15 = length
