Question

P + nx=rx-e (solve for x)

Answer 1

(p+e)/(r-n) = x

Explanation:

p + nx=rx-e

Add e to each side

p +e+ nx=rx-e+e

p +e+ nx=rx

Subtract nx from each side

p +e+ nx - nx=rx-nx

p+e = rx -nx

Factor out x

p+e = x(r-n)

Divide each side by (r-n)

(p+e)/(r-n) = x(r-n)/(r-n)

(p+e)/(r-n) = x
