From the image, the problem asks to find \(x\), \(y\), and \(z\) from the following matrix equation:

\[
\begin{bmatrix} x & 3 \\ 7 & 2 \end{bmatrix} + \begin{bmatrix} 2 - y & z \\ 2 - z & -x \end{bmatrix} = \begin{bmatrix} 3 & 7 \\ 2 & 0 \end{bmatrix}
\]

This represents an equation of two matrices, and to solve for \(x\), \(y\), and \(z\), we add the corresponding elements of the two matrices on the left-hand side and equate them to the matrix on the right-hand side. Let's break down the components.

We have:

\[
\begin{bmatrix} x + (2 - y) & 3 + z \\ 7 + (2 - z) & 2 + (-x) \end{bmatrix} = \begin{bmatrix} 3 & 7 \\ 2 & 0 \end{bmatrix}
\]

Now, equate corresponding entries:

1. \( x + (2 - y) = 3 \)  (top-left)
2. \( 3 + z = 7 \)  (top-right)
3. \( 7 + (2 - z) = 2 \)  (bottom-left)
4. \( 2 + (-x) = 0 \)  (bottom-right)

Let's solve these four equations step by step.

### 1. Solve for \(y\) from the first equation:
\[
x + 2 - y = 3 \implies x - y = 1 \quad \text{(Equation 1)}
\]

### 2. Solve for \(z\) from the second equation:
\[
3 + z = 7 \implies z = 4 \quad \text{(Equation 2)}
\]

### 3. Solve for \(z\) from the third equation:
\[
7 + 2 - z = 2 \implies 9 - z = 2 \implies z = 7 \quad \text{(Contradiction to Equation 2)}
\]

### 4. Solve for \(x\) from the fourth equation:
\[
2 - x = 0 \implies x = 2 \quad \text{(Equation 3)}
\]

With the value of \(x = 2\) in hand, let's substitute it back into the first equation to find \(y\):
\[
2 - y = 1 \implies y = 1
\]

So the solution is:
\[
x = 2, \quad y = 1, \quad z = 4
\]
