Question 567497
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!
