I work 32 hours on the weekend and now is when I have some time to reply to student questions.

You need to solve for n NOT N. Big difference between little n and big N.

P = 5n + 5w

The goal is to isolate the letter you are solving for.

Begin by subtracting 5w from both sides.

P - 5w = 5n + 5w - 5w

As you know, positive and negative terms cancel out.

So, on the right side, 5w and -5w cancel out.

We now have P - 5w = 5n.

To solve for n, divide both sides by the coefficient of n, which is 5.

Final answer: P - 5w/5 = n, which can also be written n = (P - 5w)/5

Done!
