Question: Problem finding steady states of ODEs

Hi, I'm trying to find the steady states of a pair of ODEs and have used the code below but i get the message "warning, solutions may have been lost".


> restart;

> with(LinearAlgebra);

> f := (u, v) -> (u*(1-u))-a*(u*v/(v+u);

> g := (u, v) -> b*v(a(u/(v+u))-d);

> du := diff(u(t), t) = f(u(t), v(t));

> dv := diff(v(t), t) = g(u(t), v(t));

> steadystates := solve({f(u, v) = 0, g(u, v) = 0}, {v, u});

Warning, solutions may have been lost


Can anyone see where i'm going wrong?
