Solve for n in the following equation: 4n – p = 3r

A 3r/4 + p/4

To solve for n, you have to isolate that variable by putting all of the other terms of the equation, including coefficients, integers, and variables on the other side of the equal sign.
Add p to each side of the equation:
4n – p = 3r
4n – p (+ p) = 3r (+ p)
4n = 3r + p
Divide each term by 4:
