Question
**Problem Statement:**

Find a linearly independent set of vectors that spans the same subspace of \(\mathbb{R}^3\) as that spanned by the vectors

\[
\begin{bmatrix}
3 \\
1 \\
-1
\end{bmatrix}
, \quad
\begin{bmatrix}
3 \\
2 \\
0
\end{bmatrix}
, \quad
\begin{bmatrix}
0 \\
-1 \\
-1
\end{bmatrix}
.
\]

**Solution:**

A linearly independent spanning set for the subspace is:

\[
\left\{
\begin{bmatrix}
\boxed{} \\
\boxed{} \\
\boxed{}
\end{bmatrix}
,
\begin{bmatrix}
\boxed{} \\
\boxed{} \\
\boxed{}
\end{bmatrix}
\right\}
.
\]

**Explanation:**

The original set of vectors provided spans the same subspace of \(\mathbb{R}^3\). However, to find a linearly independent set that also spans this subspace, one must choose vectors such that none can be written as a linear combination of the others. The solution leaves room for finding these values, which should be determined through methods like the row reduction or Gram-Schmidt process.
