Let the following simplex table be associated with a certain base B:

Explain how one can generate the initial array shown below from the array associated with base B, if one knows the base B and the vector of simplex multipliers ^T.

\begin{tabular}{|c|cccc:c|c|} \hline v.d. & x1 & x2 & & xn & z & t.d. \\ \hline xB & & & A & & & \\ & & & & & & b \\ \hlinez & & cT & & 1 & z \\ \hline \end{tabular} \begin{tabular}{|c|cccc:c|c|} \hline v.d. & x1 & x2 & & xn & z & t.d. \\ \hline xB & & & A & & & \\ & & & & & & b \\ \hlinez & & cT & & 1 & z \\ \hline \end{tabular}
