Question

What is the answer to 2 (n +3) = -12?

Answer 1

divide both sides by the numeric factor on the left hand side than solve... the answer is N= -9

Answer 2

2n + 6 = -12        Distributive property

2n + 6 = -12        Inverse operation
      - 6      - 6

2n = -18          

2n/2 = -18/2
n = -9

Answer: N = -9
