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

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 and finally dividing by $h$, resulting in $B = \frac{2A - bh}{h}$.
