Solving simple equations

I'm trying to solve these two simple equations but it doesn't work.

meqn = {
x'[t]==beta(x[t]+(Subscript[P,f]-p[t])),
p'[t]==(Tanh[Subscript[a,1](x[t]+(Subscript[P,f]-p[t]))+
        Subscript[a,2]x[t]]-x[t])
   };

eqp = NSolve[
meqn/.{
p'[t]->0,x'[t]->0},{p[t], x[t]
}
]

I guess I'm doing a mistake somewhere. Does anyone have idea where the mistake is?
Thank!
