To solve the given system of linear equations using the Jacobi method up to the 6th iteration, we first need to rewrite the equations in a form suitable for the Jacobi method:

The given system of equations is:

\[
\begin{cases}
9x + 2y - z = -2 \\
7x + 8y + 5z = 3 \\
3x + 4y - 10z = 6
\end{cases}
\]

### Step 1: Rewrite the equations in Jacobi form
Each equation needs to be solved for its main variable (i.e., isolate \(x\), \(y\), and \(z\)):

1. For \(x\):
   \[
   x = \frac{-2 - 2y + z}{9}
   \]

2. For \(y\):
   \[
   y = \frac{3 - 7x - 5z}{8}
   \]

3. For \(z\):
   \[
   z = \frac{6 - 3x - 4y}{-10}
   \]

### Step 2: Initial guess
We start with an initial guess, typically \(x^{(0)} = 0\), \(y^{(0)} = 0\), and \(z^{(0)} = 0\).

### Step 3: Iterations
We will perform six iterations, calculating the values of \(x\), \(y\), and \(z\) in each iteration using the equations above.

Let's calculate each iteration step-by-step using these formulas, rounding to 4 decimal places, and determine the error in the last iteration.After performing six iterations using the Jacobi method, the results are:

### Final Values (6th Iteration):
- \( x \approx -0.4850 \)
- \( y \approx 1.0123 \)
- \( z \approx -0.3407 \)

### Error in the Last Iteration:
- Error in \( x \): \( 0.0004 \)
- Error in \( y \): \( 0.0005 \)
- Error in \( z \): \( 0.0006 \)

These values and errors indicate the convergence behavior of the Jacobi method after six iterations.
