Hello! So the first thing we need to do is add 18 to both sides. When you do that, it should be 5p/7 = -25. Now, we must multiply both sides by 7/5 to isolate the “p”. -25 * 7/5 is -35. If you want to check to make sure it’s right, plug in the alleged “p” value to make sure it’s right. When we substitute “p” for -35 and we solve it by doing order of operations, we get -43. The answer is A: -35.
