Answer 2

1. Distribute
2p + 2 = 16
2. Subtract both sides by 2
2p = 14
3. Divide both sides by 2.
p = 14 / 2 = ?

Answer 3

2(p + 1) = 16
You first have to use the distributive property. So, multiply 2 by everything in the parentheses.
2p + 2 = 16
Then, subtract 2 from both sides to isolate the variable to one side.
2p = 14
Then, just divide two from both sides.
p = 7.
So, the answer is the first one. (:
