# Introducing a third output on linear programming? watch

1. This may sound like a stupid question, but i'm doing a piece of coursework for Economics on linear programming. The last part of the coursework requires you to introduce a third output, but how can I do this given that there are only 2 axis?

The only linear programming I have done involved only 2 outputs, x and y.. I have no idea how to introduce a third?

You couldn't solve it graphically in 2D, you could in 3D though. There is a method called the Simplex Method, or doing it algebraically should also be possible. If you post the question, we can help you.
