Are positive integers p and q both greater than n?
1) p - q > n
2) q > p
If I solve using analytical method in OG then I get the correct answer. But I also like to solve all inequality problems graphically. If I assume q = x and p = y and plot the two inequalities as below..
Please see the attached file for plot
(1) y - x > n {line with 45 degree slope in first quadrant passing (0,n) and feasible region above the line}
(2) x > y {line with 45 degree slope in first quadrant passing (0,0) and feasible below the line}
.. then I get infeasible solution since there is no intersection between the "shaded" regions of two inequalities (the lines are parallel). How to resolve this?
Thanks very much.
