linear programing: max Z=x+2y subject to 2.x-y>=2, x+y>=3,

[flora]

I have to calculate Z(max)= x + 2y
subject to 2.x -y ? 2, x + y ? 3, x ? 3

and then I have to write the dual problem, thank you :wink:

Re: linear programing

Draw a graph of the constraints for starters. It makes the problem easier.
