Hi
solve the system of equation  by graphing 
2x + 5y = 20   Pt(0,4) and Pt(10,0) on this Line  Blue
y = x - 3      Pt(0,-3) and Pt(3,0) on this Line  Green
Plot points for each line and connect these with the corresponding lines.

As to: 2x + 5y > 20  and  y < x – 3 
Now You may 'shade' the area above the blue 'in the area' BELOW the green 
to show the graphical solution to this system of Inequalities
Cannot demonstrate here..it would be that area between the lines on right side
