Remember you can do anything to an equation as long as you do it to both sides

5c+16.5=13.5+10c
minus 5c both sides
16.5=13.5+5c
minus 13.5 from both sides
3=5c
divide both sides by 5
3/5=c

5c + 16.5 = 13.5 + 10c

16.5 + 5c = 13.5 + 10c

16.5 + 5c = 13.5 + 10c

16.5 + 5c + -10c = 13.5 + 10c + -10c

5c + -10c = -5c 16.5 + -5c = 13.5 + 10c + -10c

10c + -10c = 0 16.5 + -5c = 13.5 + 0 16.5 + -5c = 13.5

16.5 + -16.5 + -5c = 13.5 + -16.5

:16.5 + -16.5 = 0.0 0.0 + -5c = 13.5 + -16.5 -5c = 13.5 + -16.5

13.5 + -16.5 = -3 -5c = -3

Divide each side by '-5'.

c = 0.6 or 3/5

How to find the edge length in volume?

vlada-n [284]

So we can take the volume of a cube formula and set it equal to the volume that we actually know: 64 centimeters cubed. So in order to find the length of the edge, which is a side, we need to cube root both sides of this equation. On the left-hand side, the cube root cancels all the cube.
