If A + B = ...

Question

If A + B = $⎡ ⎢ ⎣ \begin{matrix} 1 & 0 & 2 2 & 2 & 2 1 & 1 & 1 \end{matrix} ⎤ ⎥ ⎦$ and A - B = $⎡ ⎢ ⎣ \begin{matrix} 1 & 4 & 4 4 & 2 & 0 - 1 & - 1 & 2 \end{matrix} ⎤ ⎥ ⎦$
then prove that
A = $⎡ ⎢ ⎣ \begin{matrix} 1 & 2 & 3 3 & 2 & 1 0 & 0 & 2 \end{matrix} ⎤ ⎥ ⎦$ and B = $⎡ ⎢ ⎣ \begin{matrix} 0 & - 2 & - 1 - 1 & 0 & 1 1 & 1 & 0 \end{matrix} ⎤ ⎥ ⎦$
