LP Graphical Method (Multiple/Alternative Optimal Solutions)

This video shows how to solve the following linear programming problem (involving multiple/alternative solutions) using graphical method. Max Z = 5X + 10Y s.t. X + 2Y ≤ 120 X +Y ≥ 60 X – 2Y ≥ 0 X, Y ≥ 0 Linear Programming 3: Graphical Solution – with negative coefficients https://youtu.be/hNqLAwyhT-4 Linear Programming 4: Slack/Surplus, Binding Constraints, Standard Form https://youtu.be/4hp0mJgzmgc Linear Programming 5: Alternate solutions, Infeasibility, Unboundedness, & Redundancy https://youtu.be/_eMA0LWsRQQ
