Consider the following simplex tableau.
\begin{array}{c|ccccc}
& x & y & u & v & P & \text{Constants} \\
\hline
& 1 & 1 & 1 & 0 & 0 & 4 \\
& 1 & 0 & -1 & 1 & 0 & 3 \\
& 3 & 0 & 9 & 0 & 1 & 12 \\
\end{array}
Part 1 of 2
(a.) Determine whether the given simplex tableau is in final form.
Yes, the simplex tableau is in final form.
No, the simplex tableau is not in final form.
Part 2 of 2
(b.) Since the simplex tableau is in final form, write the optimal solution and the optimal value.
Optimal Solution: $(x,y) = (4, -1)$
Optimal Value: $P = 12$
