d+2g=16
Swap sides so that all variable terms are on the left hand side.
d=16-2g
Subtract 2g from both sides.
d+2g=16
Swap sides so that all variable terms are on the left hand side.
2g=16-d
Subtract d from both sides.
\frac{2g}{2}=\frac{16-d}{2}
Divide both sides by 2.
g=\frac{16-d}{2}
Dividing by 2 undoes the multiplication by 2.
g=-\frac{d}{2}+8
Divide 16-d by 2.
