Question

1.	The length of a rectangle is twice its width.  The perimeter of the rectangle is 24 inches.  Write a system of equations in 2 variables.   Use substitution to solve the problem.
A.	 Equation 1: L = 2W
     L= 2(4) = 8

Equation 2: 2L + 2W = 24
		   2(2W) + 2W = 24
		   6W = 24
		   W = 24/6 = 4

(i would like help checking the Equations)

ERquation 1. L = 2 W 2 W = L Equation 2. 2 W + 2 L = 24 Substitution: 2 W = L L + 2 L = 24 3 L = 24 L = 24 / 3 = 8 in L = 2 W 8 = 2 W 8 / 2 = W W = 4 in
