Use simplex method to solve

Maximize p = 30x + 20y+30z subject to
x + y+z <= 9
4x + 2y-2z <= 30
5x + 10y+3z <= 60

x, y, z >=0

1. I am wondering if you have a program, surely you are not contemplating doing this by hand.

3. There is also this example that describes in detail the use of the simplex tableau (by hand) for multiple constraints and variables.

It looks complicated but you will find it mechanical once you have understood it (like everything else in maths).
