what if x were negative ? Try x = -1
The inequality is not valid for any negative number x.
If you require a derivation, subtract 2x from both sides, leaving 3x>0. This is a valid operation for inequalities, and does not change the direction of the > sign.
Then divide both sidss by +3. This operation does not change the direction of the > sign either.
