Exercise 2.2.16

Answers

(a) Example of two exchanges (exchange 1 and 2, then 2 and 3):

\begin{matrix} 0 x + 0 y + 2 z = 4 \\ x + 2 y + 2 z = 5 \\ 0 x + 3 y + 4 z = 6 \end{matrix}

(b) Exchange but then breakdown (rows 1 and 3 are not consistent):

\begin{matrix} 0 x + 3 y + 4 z = 4 \\ x + 2 y + 2 z = 5 \\ 0 x + 3 y + 4 z = 6 \end{matrix}
