The image shows a 3x3 grid where you are asked to find the value of \( x \). The grid is structured like this:

\[
\begin{bmatrix}
8 & 9 & 5 \\
6 & x & 4 \\
7 & ? & 3 \\
\end{bmatrix}
\]
The question asks to calculate the value of \( x \), and there are multiple choices provided:  
a) 14, b) 10, c) 8, d) 12, e) 6.

This problem resembles a magic square where each row, column, or diagonal typically sums to the same value.

I'll proceed by solving this for you. Let's check if the sum of rows or columns follow a pattern and solve for \( x \).The value of \( x \) is 12, which corresponds to option \( \text{d} \).

Would you like further details or have any other questions?

Here are 5 related questions for practice:
1. What is the sum of the elements in each row of a magic square?
2. How would you solve for \( x \) if the problem gave sums for the diagonals instead?
3. What are the characteristics of a magic square in terms of sums?
4. Can magic squares have negative values or fractions?
5. How would you determine \( x \) if the grid was not a magic square?

**Tip:** In puzzles like these, always look for patterns, such as rows, columns, or diagonals having the same sum!
