Maximise $Z = X_1 -2X_2$
Such that
$3X_1 + X_2 \ge 3$
$2X_1 - X_2 \le 5$
$X_1, X_2 \ge 0$
I've done using CET. Find out that $\max(Z)=-6$ when $X_1=0$, $X_2=3$ which is feasible.
But i really dont know how to solve it by 2-phase method.
Is there anyone who can help me solve this?
Really thanks about that.
Regards.
