\frac{1}{2}d-4-4=5
Combine \frac{1}{8}d and \frac{3}{8}d to get \frac{1}{2}d.
\frac{1}{2}d-8=5
Subtract 4 from -4 to get -8.
\frac{1}{2}d=5+8
Add 8 to both sides.
\frac{1}{2}d=13
Add 5 and 8 to get 13.
d=13\times 2
Multiply both sides by 2, the reciprocal of \frac{1}{2}.
d=26
Multiply 13 and 2 to get 26.
