  3. 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.
