Given 3(x+7)=-12, we could do 2 things: we could distribute or divide both sides by 3. It appears that we will divide both sides by 3.

3(x+7)/3=-12/3 Divide 3 on both sides to isolate X by Division P.O.E.

x+7=-4.

Then, x+7-7=-4-7 by Subtraction P.O.E. to isolate X.

Answers

Answer:

Step-by-step explanation:

The original distance that Angel wanted to walk will be represented as A

Since we don't know the additional distance Angel walked it'll be represented as B

A= the amount of distance Angel wanted to walk

B= the amount of distance Angel wanted to walk past his/her challenge goal

C= the amount of distance Angel walked originally from to past her/his challenge goal

A+B=C
