The problem in the image is about expressing the vector \(\mathbf{v} = (2, -5, 3)\) as a linear combination of the given vectors \(\mathbf{a}_1 = (1, -3, 2)\), \(\mathbf{a}_2 = (2, -4, -1)\), and \(\mathbf{a}_3 = (1, -5, 7)\). 

To find if \(\mathbf{v}\) can be expressed as a linear combination of these vectors, we need to solve the system of equations that corresponds to:

\[
x\mathbf{a}_1 + y\mathbf{a}_2 + z\mathbf{a}_3 = \mathbf{v}
\]

This results in the following system of linear equations:

\[
\begin{align*}
x + 2y + z &= 2, \\
-3x - 4y - 5z &= -5, \\
2x - y + 7z &= 3.
\end{align*}
\]

The solution involves comparing corresponding components and forming these equations. The calculations reveal that the third equation does not align with the other two, leading to an inconsistency (\(0 = 1\)). This inconsistency means that the system has no solution, and thus \(\mathbf{v}\) cannot be written as a linear combination of \(\mathbf{a}_1\), \(\mathbf{a}_2\), and \(\mathbf{a}_3\).
