I need to make a formula in which I can find the value of x. Here is a
sample equation:

(x+2)/x=10

Any help would be appreciated.
 
You could use a formula like =(A1+2)/A1 and then use Tools/ Goal Seek to aim
for a value of 10 in the result cell by changing A1 (but that will only
approximate iteratively).
Better to use some algebra:
(x+2)/x=10
(x+2)=10*x
2=9*x
2/9=x
