You have to multiply both sides by 2 to leave x by itself so A would be the answer
Answer: Choice A) x < -36 You find this by multiplying both sides by 2. Why multply? Because this is the opposite operation that is being done on the left side (which is division). Multiplying both sides by 2 will get rid of the 2 on the left side. It will change the -18 to -36. The inequality sign will NOT flip. It only flips if you multiply both sides by a negative number. In this case 2 is positive.
