Another way to write this is 7x/8 = 21

multiply each side by 8
7x = 168
divide both sides by 7
x = 168/7 = 24
7x = 168
divide both sides by 7
x = 168/7 = 24

Oh, I get it now. Like this? :
7x / 8 = 21
x 8 x 8
7x/7 = 168/7
x = 24
7x / 8 = 21
x 8 x 8
7x/7 = 168/7
x = 24

I don't like the presentation of your second line, but you last two lines are good
If you want to show all your steps, I prefer this:
7x/8 = 21
(7x/8)(8) = 21(8)
7x = 168
7x/7 = 168/7
x = 24
If you want to show all your steps, I prefer this:
7x/8 = 21
(7x/8)(8) = 21(8)
