There are two ways to interpret this equation. Do you mean
D=C-s%2Fn+ or do you mean D=%28C-s%29%2Fn+?? What you have written technically means the first way I wrote it, but usually what is meant is the second way to write it.

If the problem is D=C-s%2Fn+, then solve it this way. Multiply both sides by n:
n%2AD=n%2AC-n%2A%28s%2Fn%29+
nD=+nC-s
Add +s to each side and subtract nD from each side:
nD%2Bs-nD+=+nC-s+%2Bs+-nD
s+=+nC-nD

You probably meant this: D=%28C-s%29%2Fn+
Multiply both sides by n:
n%2AD=n%2A%28%28C-s%29%2Fn%29+
nD=+C-s

Add +s and subtract nD from each side:
nD%2Bs+-nD+=+C-s+%2Bs+-nD
s+=+C-nD
