Answer 1

The whole point of these questions is to "isolate x". So what you do to one side you must do to the other. You want to cancel the 3 from the left by dividing it so it = 1, and if you divide on the left you must do it to the right.

Answer 2

3x=-24
x=-24/3 = -8

Answer 3

oh I thought I was supposed to subtract it from each side

Answer 4

Nope
