Chapter 6, Problem 5RE

Problems 1-7 refer to the partially completed table of the six basic solutions of the $e$ -system

$\begin{array}{l}2x_1+5x_2+s_1=32\\ x_1+2x_2+s_2=14\\ \begin{array}{ccccc}& x_1& x_2& s_1& s_2\\ \left(\text{A}\right)& 0& 0& 32& 14\\ \left(\text{B}\right)& 0& 6.4& 0& 1.2\\ \left(\text{C}\right)& 0& 7& -3& 0\\ \left(\text{D}\right)& 16& 0& 0& -2\\ \left(\text{E}\right)& & 0& & 0\\ \left(\text{F}\right)& & & 0& 0\end{array}\end{array}$

Which of the six basic solutions are feasible?
