Step-by-step explanation:

Let's look at the left side. If you move the 60 to the same side as the 72, it becomes -4x is smaller than 72-60. 72-60 is 12. Now it is -4x is smaller than 12. Since there is a negative on the left side, we flip the smaller sign to a greater sign. Then it is -4x is greater than 12. Then divide both sides by 4 for your answer to be C.
