To start off, you have to get x on one side and the numbers on the other. To do this, subtract 3 on both sides to get the +3 to the other side. After this you should have X-3X<3. Now that you have all the x values on one side, subtract them to get-2X. Now your equation is -2X<3. Now you divide to not have a coefficient before X. To do this divide by -2. Keep in mind that when you divide by a negative number in an inequality, the sign flips. Because of this your answer would be X>-3/2.
