NDSolve with implicit function

I am trying to numerically solve a differential equation
{x'[t]==f[x[t],y[t]], x[0]=a} , where y[t] is the numerical solution to an
implicit function g[x[t],y[t]]==0 (not a polynomial).

In other words, given x[t], we should be able to numerically compute y[t]
from the implicit function and it would enter numerically into the function
f of NDSolve.

Anyone with an idea on how to do this?
