Solve for the specified variable

Question

P=(R-C)/n for C

Answer 1

The equation is P = (R - C)/n and solve for C.

Multiply each side by n.

P * n = [(R - C)/n] * n

P * n = R - C

Subtract R from each side.

Pn - R = R - C - R

Pn - R = - C

Multiply each side by negative one.

(Pn - R) * (-1) = (-C) * (-1)

R - Pn = C

The value of C = R - Pn.
