B=16x+6
Combine 21x and -5x to get 16x.
16x+6=B
Swap sides so that all variable terms are on the left hand side.
16x=B-6
Subtract 6 from both sides.
\frac{16x}{16}=\frac{B-6}{16}
Divide both sides by 16.
x=\frac{B-6}{16}
Dividing by 16 undoes the multiplication by 16.
x=\frac{B}{16}-\frac{3}{8}
Divide B-6 by 16.
B=16x+6
Combine 21x and -5x to get 16x.
