Here it the answer to you question Lenona
I think you must have deleted it because I cannot see the question anymore but you can have the answer anyway :)
------------------------------------------------------
6x=38
You need to get the x on its own so you need to get rid of the 6
At the moment it is 6×x There is an invisable times sign between the 6 and the x.
The opposite of times is divide.
So you will need to DIVIDE BOTH SIDES BY 6.
⧸6x⧸6=38÷6
Note that a fraction line IS a divide sign. They are really the same thing.
If you look at the divide sign ÷ you can see how you could replace the dots with numbers and you would have a fraction. :)
