I don't know how to do this exercise:
Minimize-2x1 + x2 -x3
s.t x1+2x2+x3<=8
-x1+x2-2x3<=4
x1,x2,x3>=0
Final table:
Base z | x1 | x2 | x3 | x4 | x5 | RHS
z | 1 | 0 | 3 | 3 | 2 | 0 | 16
x1 | 0 | 1 | 2 | 1 | 1 | 0 | 8
x5 | 0 | 0 | -1 | 1 | 1 | 1 | 12
sopuse that the following constraint is added to the proble: x2+2x3=3. Using sensitivity analysis, finde the new optimal solution.
