Solve using the addition and mulitplication method principles. 4+9x<13. Is this right? 44 +9x<134
9x/9> 9/9
x>1?

No, you should not have changed the direction of the <, since you divided by a positive number.

almost, the < sign only changes to a > sign when both sides are multiplied by a minus.
so the answer is x<1
Hope that helps
