EDIT:EDIT: I found what I was looking for. Thanks!

eq:=(V^(1-r/(r-s))*V*k/(r-2*s)+_C1)*V^(r/(r-s))=0;

solve(eq,C1);

Can anyone tell me why nothing happens when I solve the above equation for C1.

I've been coming across this problem a few times lately, but sometimes when the equations are less complicated it does work from time to time.

Any help would be greatly appreciated.

EDIT: Thanks Markiyan Hirnyk.

But I'm still having some trouble.

**f:=t->(-r*t+s*t+V)^(r/(r-s));**

**eq2:=diff(C*f(t),t)+C*f(t)*r/(V+s*t-r*t)=s*k*t;**

**solve(eq2,C);**

When I try solving eq2 nothing happens.

This time C is just a variable I used and not one Maple generated.

So why doesn't it work with this particular equation?
