3A=7K-2P-4B
Subtract 4B from both sides.
3A=-4B+7K-2P
The equation is in standard form.
\frac{3A}{3}=\frac{-4B+7K-2P}{3}
Divide both sides by 3.
A=\frac{-4B+7K-2P}{3}
Dividing by 3 undoes the multiplication by 3.
4B=7K-2P-3A
Subtract 3A from both sides.
4B=-3A+7K-2P
The equation is in standard form.
\frac{4B}{4}=\frac{-3A+7K-2P}{4}
Divide both sides by 4.
B=\frac{-3A+7K-2P}{4}
Dividing by 4 undoes the multiplication by 4.
B=\frac{7K}{4}-\frac{P}{2}-\frac{3A}{4}
Divide 7K-2P-3A by 4.
