Level curves to two functions (Contour plot)

I want to solve a system of nonlinear equations:

x^2 + y*sin(y) - 3 = 0 x*y + exp(x) + y -5 = 0

So I introduced the two functions f1 = x^2 + y*sin(y) - 3 and f2 = x*y + exp(x) + y -5. Now I am trying to plot the level curves(at 0) so I can see how many solutions exists. But I am unable to plot a meaningful result(i.e finding the intersections).

     %
x=linspace(-15,15,400); 
y=linspace(-15,15,400);
f=@(x,y)(x.^2+y.*sin(y)-3);
[X,Y]=meshgrid(x,y);
Z=f(X,Y);
contour(X,Y,Z,10)
hold on
f=@(x,y)(x.*y+exp(x)+y-5);
[X,Y]=meshgrid(x,y);
Z=f(X,Y);
contour(X,Y,Z,10)
  end

PLEASE don't just ask the same question repeatedly. The only thing you changed here was to remove the useless "if true". Anyway why was my answer to your last (virtually identical) question inadequate?
