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 x₁ > 0 and x₂ > 0, you will get x1=-1.5 and x2=16.5, which is where the first two constraints intersect.
