Could someone help me solve this problem using the Big M method? (Yes, it's my homework, I've been working on it for a while but it doesn't go anywhere)
Maximize P = 5x1 + 7x2 + 9x3
subject to x1 - x2 + x3 >= 20,
2x1 + x2 + 5x3 = 35,
x1,x2,x3 >= 0

Can you verify that your conditions are correct? I don't believe there is any combination of x1, x2, and x3 that will meet all three conditions.
@DrewDad,
That's what I have. Positive.
