Just set each expression equal to 3(n+6). If you get the same answer on both sides (x=x) then that expression is equivalent! :)

Answer:

n=-6

Step-by-step explanation:

Equate the equation to zero

3(n+6)=0

Open the bracket

3n+18=0

Substrate 18 from both sides

3n=-18

Divide both sides by 3

n=-6

Therefore the answer to that given equation is -6
