2(p + 1) = 18. ****We will be using distributive property to solve for this equation.
2(p + 1) = 18
2p + 2 = 18 ***now, we want to get rid of the 2 from the left side so we will subtract 2 from both sides.
2p + 2 - 2 = 18 - 2
2p = 16. ****Now, we can divide both sides by 2 because we want to get rid of the 2 from the left side so that we are just left with P and our answer.
2p = 16
2p/2 = 16/2
P = 8
So, in conclusion, P is equal to 8.
