![## Matrix Equation Problem
### Problem Statement:
Solve for \( u \), \( x \), \( y \), and \( z \) in the given matrix equation.
### Given Matrix Equation:
\[
\begin{bmatrix}
3x - 3 & 4 & 3 \\
3 & 9 & y - 3 \\
3z & -4 & 3
\end{bmatrix}
\begin{bmatrix}
4 & u & 3 \\
3 & 9 & 6 \\
9 & -4 & 3
\end{bmatrix}
\]
### Solution Steps:
1. Identify the corresponding elements in the left and right matrices of the provided matrix equation.
2. Solve for each variable that appears in the equation to find the values of \( u \), \( x \), \( y \), and \( z \).
### Equations to Solve:
- To find \( u \):
\[ 3 = u \]
- To find \( x \):
\[ 3x - 3 = 4 \]
\[ 3x = 7 \]
\[ x = \frac{7}{3} \]
- To find \( y \):
\[ y - 3 = 6 \]
\[ y = 9 \]
- To find \( z \):
\[ 3z = 9 \]
\[ z = 3 \]
### Final Result:
\[
\begin{align*}
u &= 3 \\
x &= \frac{7}{3} \\
y &= 9 \\
z &= 3
\end{align*}
\]
Enter these values in the spaces provided:
- \( u = 3 \)
- \( x = \frac{7}{3} \)
- \( y = 9 \)
- \( z = 3 \)](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F2c4f1739-57e2-4399-a976-93f96ef5c2b4%2Fed919372-24bb-4b4f-b570-a6ffab0a2809%2Fy9l0oo_processed.jpeg&w=3840&q=75)
