Simplex method in prime how to use the constrains maximise s.t. constraints.

[Anthony The Koala]

Dear all, thank you for replies.

Here is what I tried:

HP Carnace macro to solve a simplex. Could you please share the link to the TORA macro.


To DG1969, I created the entry in the afvanced menue
V1 6x + 5y
Subject to:
V2 x >= 0,
V3 y >= 0
V4 2x + 4y >= 22
V5 3x + 2y >= 20
V6 4x + 5y >= 40

I made another line
V7. V4 AND V5 AND V7

Pressed plot
Result: "Error Invalid Object"
Is there or are there additional steps?

To Albert Chan,
* I mentally made a note of the slopes
* there were three equations for two unknowns I ranked the magnitude of the slopes
* used the Linear Solver app and entered the two equations to obtain the soln to X and Y
*,X = 2.85714, Y = 5.7143
* then in the home screen subtituted the formula X*6 + 5*Y = 45.713

Thank you all
