pls help as soon as possible For the Big$-$M tableau $($of a minimization LP and row$0$ at bottom$),$

$\left[\begin{array}{cccccccc}z& x_1& x_2& x_3& s_1& e_2& a_2& RHS\\ 0& 1& 0\mathrm{.}3& -1& 1& 0& 0& 10\mathrm{.}9\\ 0& 0\mathrm{.}1& 1\mathrm{.}4& 1& 0& -1& 1& 10\mathrm{.}8\\ 1& -4\mathrm{.}7& -2\mathrm{.}3& -10& 0& 0& -100& 0\end{array}\right]$

perform the simplex algorithm to find the optimal tableau.
