Question
The image depicts a system of linear equations and how it can be represented in vector notation. 

The equation given is:
\[ -2x - 7y - 3z = 16. \]

Accompanying this equation is a vector representation of the system of equations, indicating a combination of vectors with scalar multiples. 

The vector representation is structured as follows:
\[ 
\begin{bmatrix}
x \\
y \\
z
\end{bmatrix}
=
\begin{bmatrix}
\text{[blank]} \\
\text{[blank]} \\
\text{[blank]}
\end{bmatrix}
+
s
\begin{bmatrix}
\text{[blank]} \\
\text{[blank]} \\
\text{[blank]}
\end{bmatrix}
+
t
\begin{bmatrix}
\text{[blank]} \\
\text{[blank]} \\
\text{[blank]}
\end{bmatrix}
\]

In this notation:
- \( x \), \( y \), \( z \) are variables representing coordinates or scalar quantities in a vector.
- The blanks in each vector indicate the coefficients or values that need to be determined or added to make up the vectors.
- \( s \) and \( t \) are scalar multiples that scale the corresponding vectors in the linear combination.

This representation is useful for understanding systems of equations in terms of vector spaces and linear algebra, providing a more geometric interpretation of solutions to the equations.
