without out an equal sign you can't solve for x, but you can simplify it to
Explanation:
I scan the problem to see if I can simplify any terms. Two things jumped out at me.
first on the bottom of the second fraction I can factor out a 2 from
Then I noticed the terms on top of the first fraction can be written as the difference of two squares. http://www.purplemath.com/modules/specfact.htm) .
So I rewrote
The problem now looks like:
Start by canceling out anything that the same on any part of top and bottom.
Next I see there is a 12 on the top and a 3 on the bottom. I can divide 12 by 3 to get 4. The problem now look like this
Now I divide the 4 by 2 and get
Write the equation and you get
If you need any more explanation please just let me know.
Because this is not an equation you cannot solve for

Explanation:
First, factor the denominator of the fraction on the left with the numerator of the fraction on the right:
Next, factor and cancel the common terms for the numerator of the fraction on the left and the denominator of the fraction on the right:
If necessary, we can split this result into two fractions as:
