g =$\frac{2A}{h}-f$

Work Step by Step

The first step is to divide each side of the equation by h: $\frac{A}{h}$=$\frac{f+g}{2}$ Next, multiply each side of the equation by 2 to get: $\frac{2A}{h}$= f+g Lastly, subtract f from both sides to get g by itself, giving you the answer: $g=\frac{2A}{h}-f$
