7x over 8 (fraction = 21


I don't know how to solve this.
Answered by Katalina
Another way to write this is 7x/8 = 21
Answered by Reiny
multiply each side by 8

7x = 168
divide both sides by 7
x = 168/7 = 24

7x/8 = 21

Multiply both sides by 8.

7x = 168

x = 24

How does 7x = 168?
Answered by Katalina
Oh, I get it now. Like this? :

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
