x>5

Explanation:

You use this property: an inequality holds if and only if, for any number #x#, the inequality obtained by adding #x# to both sides holds. This means that we can add (or subtract) any number we want from an inequality. In your case, the good idea is to add #3# to both sides, since we obtain

#x-3+3>2+3#

and therefore

#x>5#
