The volume of a cube is L^3 where L is a side length. Here we have 2 identical cubes so
128=2L^3. Divide by 2 then
64=L^3. Take cube root of both sides to get
L=4
Answer: x=5 y=-6
(5,-6)
Step-by-step explanation:
Solve by elimination

multiply x-5y=35 by 3
= 3x-15y=105


-

divide 9 on both sides
y= -6
Now solve for x
you must plug in -6 for y in either equations
i plugged in -6 for y in 3x-15y=105




subtract 90 on both sides
