Show that the minimum of Z occurs at more than two points : Maximise `Z = x + y`, subject to `x-ylt=-1,-x+ylt=0,x , ygeq0`.

Text Solution

Verified by Experts

We can draw the graph for these two lines,
`x-y = -1` and `-x+y=0`
Please refer to video for the graph.
As shown in the video, there is no common area between these two inequalities.
So, there can not be any maximum value for Z.
