Solve showing work

don't understand : (

This is actually a very simple problem when you understand how to do it.

First, I would add the 12 to both sides. 
Equation would now look like this x/6=24 
Then I would do the inverse (opposite) of division which is multiplication. 
So multiply 6 to both sides so we can get the x alone. 6*12=144
Now x is alone, and X = 144. 
Feel free to ask me questions!

If there are four friends then each would get, 1.25 or 1 1/4. so this is how i solved 5 ÷ 4 = 1.25 . hope this ; )
