w=\frac{1}{2}+\frac{1}{8}c
Divide each term of 4+c by 8 to get \frac{1}{2}+\frac{1}{8}c.
\frac{1}{2}+\frac{1}{8}c=w
Swap sides so that all variable terms are on the left hand side.
\frac{1}{8}c=w-\frac{1}{2}
Subtract \frac{1}{2} from both sides.
\frac{\frac{1}{8}c}{\frac{1}{8}}=\frac{w-\frac{1}{2}}{\frac{1}{8}}
Multiply both sides by 8.
c=\frac{w-\frac{1}{2}}{\frac{1}{8}}
Dividing by \frac{1}{8} undoes the multiplication by \frac{1}{8}.
c=8w-4
Divide w-\frac{1}{2} by \frac{1}{8} by multiplying w-\frac{1}{2} by the reciprocal of \frac{1}{8}.
w=\frac{1}{2}+\frac{1}{8}c
Divide each term of 4+c by 8 to get \frac{1}{2}+\frac{1}{8}c.
