I think the answer is 24x-5
The answer is -5, -5 added by 5 cancels each other out. Then when you add 4x + 8x, you get 12x. So when you do 12x= -60, you get -5.
Square A:
Length = 13 inches
Height = 2 inches
Volume: 23 inches
-----------------------------
Square B:
Length = 5 inches
Height = 2 inches
<span>Volume: 10 inches
</span>
23 x 10 = <span>230 inches
</span>
VOLUME: 230 inches
I think the equation is
y=-1/3x +10/3
(1/3x+y=10/3)•3
x+3y=10, is the answer
