I tried rearranging the equation to get:

$\displaystyle x = 1/2 Ab$

I mulitplied 1/2 Ab through but I did not end up with the correct answer.

What am I doing wrong?

Any help is appreciated!

$\displaystyle 2A^{-1}\begin{pmatrix}x\\y\\z\end{pmatrix}=\begin{pmatr ix}1\\0\\1\end{pmatrix}$ . Multiply both sides by $\displaystyle A$ :

$\displaystyle 2\begin{pmatrix}x\\y\\z\end{pmatrix}=A\begin{pmatr ix}1\\0\\1\end{pmatrix}=\begin{pmatrix}0\\6\\6\end {pmatrix}$ ...end it now.
