[itex]\frac{\partial r}{\partial t} = Q\frac{\partial c}{\partial t}[/itex]

Obviously, r depends on c and visa versa, but they both depend on time. Is there a way to uncouple these variables and solve the equation, so that I get r(t) and c(t)?

To me, this really seemed trivial at first, but I've spent hours solving this using decoupling recipes I found all over the internet, but I just can't get it to work (which is frustrating). Could you please help me out?
