Step 1
To set up the initial simplex tableau, we first convert the maximization problem into a minimization problem by multiplying both sides of the objective function by -1:
minimize:
subject to:
We introduce slack variables s1 and s2 to convert the inequality constraint into an equality constraint:
2x1 + 2x2 + 3x3 + s1 = 1 x1 + s2 = 0 x2 = 0 x3 = 0
The initial simplex tableau is:
z | x2 | x2 | x3 | s1 | s2 | RHS |
1 | 2 | 2 | 3 | 1 | 0 | 1 |
0 | 1 | 0 | 0 | 1 | 0 | 0 |
0 | 0 | 1 | 0 | 0 | 1 | 0 |
0 | 0 | 0 | 1 | 0 | 0 | 0 |
-21 | 22 | 0 | -3 | 0 | 0 | 0 |
