Solve the following system of inequalities by graphing.
5x  4y ≥ 20
3x  2y ≤ 8
y ≥ 3
I need help, like a website or steps on how to do this. I don't get it, at all.

Graph each inequality as if it were a line like 5x  4y≥20 becomes y =5/4 x +5 crosses the y axis at 5 and has a slope of 5/4. Put (0,0) in the inequality y≤5/4x +5 if the inequality is true shade the side of the line that has (0,0) on it. Do the same for the remaining inequalities. For y≥3 shade above the horizontal line where y = 3.

Okay, thanks. I think i get it
