First, they are the same question.
Second, I present- the un-confusingified problem-
\(If\ there\ exists\ a\ matrix\ \mathbf{A}\ such\ that\ \mathbf{A} \\\begin{pmatrix} 1 \\ 0 \\ 0 \end{pmatrix} = \begin{pmatrix} -3 \\ 4 \\ 0 \end{pmatrix},\mathbf{A} \begin{pmatrix} 0 \\ 1 \\ 1 \end{pmatrix} = \begin{pmatrix} 1 \\ 2 \\ 3 \end{pmatrix}, \mathbf{A} \begin{pmatrix} 1 \\ 1 \\ 1 \end{pmatrix} = \begin{pmatrix} 3 \\ 2 \\ 1 \end{pmatrix} \\calculate\ \mathbf{A} \begin{pmatrix} 1 \\ -1 \\ -1 \end{pmatrix}. \\If\ there's\ no\ such\ matrix,\ answer\ with\\ \begin{pmatrix}? \\ ? \\ ? \end{pmatrix}.\)
Hope This Helps!

Sorry the mathbf stuff were on my nerves.
