ContourPlot3D: plot implicitly defined surfaces


Given two functions F=F(x,y;a,b) and G=G(x,y;a,b), the relations

 F(x,y;a,b)=0, and
{
 G(x,y;a,b)=0

implicitly define another two functions x=x(a,b) and y=y(a,b). Suppose
functions F and G are implicit and transcendental, it is cumbersome to
get x and y simultaniously from F=0 and G=0. Is it possible to plot
surfaces x=x(a,b) and y=y(a,b) according to F=0 and G=0 by means of
ContourPlot3D?
Any suggestion and advice will be appreciated.
