Answers

[\begin{matrix} 1 & - 1 \\ 1 & 1 \\ 1 & 2 \end{matrix}] [\begin{matrix} C \\ D \end{matrix}] = [\begin{matrix} 7 \\ 7 \\ 21 \end{matrix}] .

The solution $\hat{x} = [\begin{matrix} 9 \\ 4 \end{matrix}]$ comes from

[\begin{matrix} 3 & 2 \\ 2 & 6 \end{matrix}] [\begin{matrix} C \\ D \end{matrix}] = [\begin{matrix} 35 \\ 42 \end{matrix}] .
