Solve the formula for the specified variable.
-$A = \frac { 1 } { 2 } h ( B + b ) \quad$ for $b$
A) $b = \frac { 2 \mathrm {~A} - \mathrm { Bh } } { \mathrm { h } }$
B) $b = 2 A - B h$
C) $b = \frac { A - B h } { h }$
D) $b = \frac { 2 \mathrm {~A} + \mathrm { Bh } } { \mathrm { h } }$

To solve for $b$, first multiply both sides by 2 to get rid of the fraction: $2A = h(B + b)$. Then, isolate $b$ by subtracting $Bh$ from both sides: $2A - Bh = hb$. Finally, divide both sides by $h$ to solve for $b$, resulting in $b = \frac{2A - Bh}{h}$.
