Question

Please help me and explain it​

Answer 1

Divide both sides by -3.

Explanation:

This question is asking you how to get from step 1:
`-3(p-7) = -15` to step 2:
`p - 7 = 5`.

We can see that the expression inside of the parentheses (p - 7) didn't go away from step 1 to step 2, and the term that was being multiplied by (p-7) had gone away. The only way you can "get rid" of a multiplied term is by doing the inverse of multiplication, which is division. Thus, you have to divide both sides by -3 to get to step 2.
