Step-by-step explanation:

Step 1: Define

$\displaystyle N = S(P - V) - F$

Step 2: Solve for S

Rearrange.

1. [Addition Property of Equality] Add F on both sides:                                   $\displaystyle N + F = S(P - V)$
2. [Division Property of Equality] Isolate S:                                                       $\displaystyle \frac{N + F}{P - V} = S$
3. Rewrite:                                                                                                           $\displaystyle S = \frac{N + F}{P - V}$
