D. n = 4p
Step By Step:
Equation: 13n -6p -11n = 2p
1st: Combine like terms (things that are similar) If you do it correctly you get
2n - 6p = 2p
2nd: add 6p to both sides because you need to get rid if it on the left side and what you do to one side you have to do to the other.
You will get 2n = 2p + 6p (or just 8p)
3: 2n = 8p
divide both sides by 2
answer: n = 4p
