The image contains a 3x3 matrix, and the task is to calculate the value of \(x\) based on a specific pattern or rule applied to the matrix.

The matrix is as follows:

\[
\begin{matrix}
8 & 9 & 5 \\
6 & x & 4 \\
7 & 6 & 3 \\
\end{matrix}
\]

Options for the value of \(x\):
- a. 14
- b. 10
- c. 8
- d. 12
- e. 6

Let's analyze if there is a consistent pattern within the matrix, possibly by rows, columns, or diagonals.

Let me calculate and verify the pattern.Analyzing the matrix based on the sums:

- Row sums:
  - First row: \( 8 + 9 + 5 = 22 \)
  - Second row: \( 6 + x + 4 \) (missing value of \(x\))
  - Third row: \( 7 + 6 + 3 = 16 \)

- Column sums:
  - First column: \( 8 + 6 + 7 = 21 \)
  - Second column: \( 9 + x + 6 \) (missing value of \(x\))
  - Third column: \( 5 + 4 + 3 = 12 \)

- Diagonals:
  - Main diagonal: \( 8 + x + 3 \) (sum is 11 without \(x\))
  - Other diagonal: \( 5 + x + 7 \) (sum is 12 without \(x\))

Given these sums, the second row should have the same sum as the first or third row, which is likely 16. Thus, for the second row to sum to 16:
\[
6 + x + 4 = 16
\]
Solving this:
\[
x = 16 - 6 - 4 = 6
\]

Therefore, \(x = 6\).

Here are 5 related questions for further practice:
1. What pattern emerges if the matrix columns should have equal sums?
2. How can diagonal sums help identify missing values in a matrix?
3. Can the value of \(x\) be derived from the column sums?
4. How would the solution change if \(x\) were placed in a different position of the matrix?
5. What is the significance of ensuring balanced sums in puzzles like this?

**Tip**: When solving matrix puzzles, look for consistent patterns across rows, columns, and diagonals to find missing values.
