3x[1]+x[2]<=12,x[1]+x[2]<=15,z=2x[1]+x[2]

I need the simplex for this problem. I have the right answer but keep coming up with a differant answer. This in our book as a practice problem.

Do you have the answer?

Since you have not given the extra constraints x_{1} > 0 and x_{2} > 0, you will get x1=**-**1.5 and x2=16.5, which is where the first two constraints intersect.

Possible extra constraints:

x_{1} ≥ 0

x_{2} ≥ 0
