The answer is 6 inches, 3*3*3 equals 27, the current volume of the cube, 27*8 equals 216, the new volume, 6*6*6 equals 216, so the side lengths equal 6 inches.
1. 8p-3=13
+3
8p=16 /8
p=2
2. 8j -5 +j=67
== 9j=72 /9
j=8
3. 3(2x-5)=4x+33 <--- =expand ()
6x-15=4x+33 ---> 2x=48
x=24
4. c=b-bx
get just x's on one side
c-b=bx
divide by b---> (c-b)/b=x
