Let's rewrite the expression as
So, if 
, you may divide both sides by 
, the equation becomes 
, and the only solution is 
, which means that this is not an identity (an indentity is tautologically true, no matter the value of x).
If instead 
, you are multiplying both sides by zero, so the equation becomes
So, it doesn't matter which value for x you choose, because you will always end up with 
, which is obviously always true.
