Expert Solution

Step 1

The given matrix and the vectors,

$A = [\begin{matrix} 1 & 2 \\ 8 & 18 \end{matrix}], b_{1} = [\begin{matrix} - 4 \\ - 28 \end{matrix}], b_{2} = [\begin{matrix} 1 \\ - 2 \end{matrix}], b_{3} = [\begin{matrix} - 2 \\ - 22 \end{matrix}], a n d b_{4} = [\begin{matrix} 0 \\ - 12 \end{matrix}]$
