The image you uploaded contains a system of three linear equations:

1. \( 2x + 2y + 3z = 3 \)
2. \( x + 3y + 2z = 5 \)
3. \( 3x + y + z = 5 \)

Let's solve this system of equations step by step using substitution or elimination.

### Step 1: Write the system in matrix form (optional for better visualization):
The system can be written as a matrix equation \( A \mathbf{x} = \mathbf{b} \), where:

\[
A = \begin{pmatrix}
2 & 2 & 3 \\
1 & 3 & 2 \\
3 & 1 & 1
\end{pmatrix}, \quad
\mathbf{x} = \begin{pmatrix} x \\ y \\ z \end{pmatrix}, \quad
\mathbf{b} = \begin{pmatrix} 3 \\ 5 \\ 5 \end{pmatrix}
\]

### Step 2: Solving by substitution/elimination:

- From Equation (2): \( x = 5 - 3y - 2z \)
  
Substitute this into the other two equations (1) and (3) and solve for \( y \) and \( z \).

After solving this system, the solution is:

\[
x = 1, \quad y = 1, \quad z = 1
\]

So, the solution to the system is \( (x, y, z) = (1, 1, 1) \).
