"Solve for s" means to get s all by itself on one side of the equals sign. Right now the equation is solved for D.
D = C - s/n
So first step, add s/n to both sides of the equation.
s/n + D = C
Then subtract D from both sides.
s/n = C - D
Finally, multiply both sides by n:
s = n(C-D)
I am not sure what you mean about depreciation, but the formula is "solved for s" above.

First: eliminate the fraction > multiply the denominator by everything ...
D(n) = n(C) - n(s/n)
Sec: cancel "like" terms and combine the remaining terms...
Dn = Cn - s
Third: solve for "s" by subtracting Cn from both sides (opposite side means opposite sign)...
Dn - Cn = Cn - Cn - s
Dn - Cn = -s
-s = Dn - Cn
*Make sure the coefficient "s" is positive > change all the signs in the equation...
s = -Dn + Cn
Or, s = -n(D - C) but, in this problem, there's no need to factor and solve for any variable.

Add s/n to both sides:
D+s/n=C
Subtract D from both sides:
s/n=C-D
Multiply n from both sides:
s=n(C-D)

n(D=C-s/n)
Dn=Cn-s
s=Cn-Dn
