Visualizing the difference curve in a 2D plot?

$begingroup$
I have two functions $f(x,y)$ and $g(x,y)$. I wish to perform two tasks on a 2-dimensional figure:
Plot the curve where each point satisfies $f(x,y)=g(x,y)$.
Mark one side of the curve with red.
I tried to use Plot3D like the following
myfunc[x_, y_]:= If[f[x, y] < g(x, y), 1,0];
Plot3D[myfunc[x, y], {x, 0, 10}, {y, 0, 3}]
It gives what I expected, but how can I do this in a 2D plot?
