The system of equations is given by:
\[\begin{aligned}
x+2z= 3 & &
\\2x -y+ z = 2& &
\\3x -2 y -z= 1 & &
\end{aligned}\]
When solving the system using Cramer's rule, we evaluate determinants of four matrices. What is the arithmetic mean of all these determinants?
\(2
\)
\(3.5
\)
\(\frac73
\)
\(\frac83
\)
