**Matrix Addition Exercise**

**Instruction:**
Use the given matrices to find the expression.

**Given:**

\( A = \begin{pmatrix} 3 & 4 & 9 \\ 6 & 9 & 3 \\ 7 & 2 & 8 \end{pmatrix} \)

\( C = \begin{pmatrix} 7 & 7 & 3 \\ 3 & 8 & 1 \\ 4 & 1 & 1 \end{pmatrix} \)

**Expression:**
\( A + C \)

**Solution Template:**

\( A + C = \begin{pmatrix} \text{[ ]} & \text{[ ]} & \text{[ ]} \\ \text{[ ]} & \text{[ ]} & \text{[ ]} \\ \text{[ ]} & \text{[ ]} & \text{[ ]} \end{pmatrix} \)

**Task:**
Fill in the blanks by performing the addition of corresponding elements from matrices \( A \) and \( C \).
