To solve the given system, we need to express the vector \([x_1, x_2, x_3, x_4, x_5, x_6]\) as a linear combination of the given vectors and parameters \(s\), \(t\), and \(u\). This involves setting up a system of linear equations based on the components of the vectors and solving for the unknowns \(s\), \(t\), and \(u\).
Step 1: Set Up the System of Equations
We are given a system of equations based on the linear combination of vectors. The equations are:
\[
\begin{align_}
s + 2t + 3u + 1 &= 10, \\
s + 2t + 3u + 2 &= 20, \\
s + 2t + 3u + 3 &= 30, \\
s + 2t + 3u + 4 &= 40, \\
s + 2t + 3u + 5 &= 50, \\
s + 2t + 3u + 6 &= 60.
\end{align_}
\]
Step 2: Simplify the Equations
Each equation can be simplified by subtracting the constant term on the right-hand side:
\[
\begin{align_}
s + 2t + 3u &= 9, \\
s + 2t + 3u &= 18, \\
s + 2t + 3u &= 27, \\
s + 2t + 3u &= 36, \\
s + 2t + 3u &= 45, \\
s + 2t + 3u &= 54.
\end{align_}
\]
Step 3: Analyze the System
The simplified equations are inconsistent because they suggest that the same expression \(s + 2t + 3u\) equals different values (9, 18, 27, 36, 45, 54). This indicates that there is no solution to the system of equations as it stands.
