**Problem 16.** Construct a matrix with the required property or say why it is impossible.

(a) Column space contains 
\[
\begin{bmatrix} 1 \\ 2 \\ -3 \end{bmatrix}
\]
and
\[
\begin{bmatrix} 2 \\ -3 \\ 5 \end{bmatrix}
\],
and nullspace contains
\[
\begin{bmatrix} 1 \\ 1 \end{bmatrix}
\].

(b) Row space contains 
\[
\begin{bmatrix} 1 & 2 & -3 \end{bmatrix}
\]
and
\[
\begin{bmatrix} 2 & -3 & 5 \end{bmatrix}
\],
and nullspace contains
\[
\begin{bmatrix} 1 \\ 1 \\ 1 \end{bmatrix}
\].

(c) \( Ax = \begin{bmatrix} 1 \\ 1 \\ 1 \end{bmatrix} \) has a solution and
\[
A^T \begin{bmatrix} 1 \\ 0 \\ 0 \end{bmatrix} = \begin{bmatrix} 0 \\ 0 \\ 0 \end{bmatrix}
\].
