Find solutions of linear system

**DarK** · February 19th 2010, 12:41 PM

I tried rearranging the equation to get:

$x = 1/2 Ab$

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!

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

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