P = r-c/n (This is kinda unclear - is the divided sign under the c or under the r-c, if so write as (r-c)/n, but in this problem I will assume it is P = r - (c/n))

Anyways, we minus the r from both sides to get

P-r = -c/n

Then, we multiply both sides by n to get

n (P-r) = -c

We multiply both sides by -1 to get rid of the negative sign of the c.

-n(P-r) = c

We can write this as either

c= -n(P-r)

or c = nr- PN
