d=64in
Multiply 8 and 8i to get 64i.
64in=d
Swap sides so that all variable terms are on the left hand side.
\frac{64in}{64i}=\frac{d}{64i}
Divide both sides by 64i.
n=\frac{d}{64i}
Dividing by 64i undoes the multiplication by 64i.
n=-\frac{id}{64}
Divide d by 64i.
d=64in
Multiply 8 and 8i to get 64i.
