Question
Is this a subspace of R3? Please explain it.
**Vector Definition and System of Equations**

The image describes a set \( V \) of vectors, where each vector \(\begin{bmatrix} a \\ b \\ c \end{bmatrix}\) satisfies the following system of linear equations:

1. \( a + b + c = 2 \)
2. \( 3a - c = 1 \)
3. \( a - b + c = 3 \)

This notation is often used in linear algebra to define a subspace or solution set in \(\mathbb{R}^3\), the three-dimensional real coordinate space. The conditions ensure that any vector \(\begin{bmatrix} a \\ b \\ c \end{bmatrix}\) in the set \( V \) simultaneously satisfies all three equations.
