See explanation.


To solve the problrm graphically means to plot function graphs in the single coordinate plane and look for points where the graphs meet.


To graphically solve a system:


you have to draw two graphs on a single coordinate plane:

graph{(x+y-7)(x-y-5)=0 [-0.875, 19.125, -4.88, 5.12]}

The graphs cross at the point #(6,1)# this means that the system has a solution:
