Show solution of 3 simultaneous linear equations

Hi folks,

I have some code that plots the intersection of 3 planes representing 3 linear equations. Is there some way of improving the graphical plots to help see the solution intersection? Transparency etc?

syms x y z
ezsurf(3*x + 2*y-19, [10,-10]); hold on;
ezsurf((2*x + 4*y-32)/5, [10,-10]); hold on
ezsurf((4*x -y-4)/2, [10,-10])

Thanks in advance B
