## Homework Statement

Question in the image.

## Homework Equations

I got a but can seem to get the answer for b which is $$\vec{x} = c\begin{pmatrix} 1 \\ 0\end{pmatrix}$$

where for any scalar c

## The Attempt at a Solution

I managed to get it to $$\vec{x}(A-1)=0$$

$$= \begin{pmatrix} 0 3 \\ -1 0\end{pmatrix}=\begin{pmatrix} 1 0 \\ 0 1\end{pmatrix}$$

Then I reduced the matrix to reduced row echolon form

but after that I seem not to get the answer.

Thank you
