Thandi started with a solid stack of cubes. 5 cubes long, 5 cubes wide and 3 cubes high. How many cubes did Thandi use to make a solid stack of cubes?

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16
