How to find the coordinates of the vertices of a triangle using fzero?

Question

MATLAB

In my task it says: find the coordinates of the vertices of a triangle whose sides are described by the equation: (AB) 3x-5y-1=0, (BC) 5x+y+12=0, (AC) 2x+5y-12=0;
The problem is that I can find the coordinates of the vertices, but with fslove, but with fzero I can’t. Help if not difficult.
