Solve system of linear equations, using matrix method,
`x - y + z = 4" "``2x + y - 3z = 0" "``x + y + z = 2`

Explanation

To solve the system of linear equations using the matrix method, we will follow these steps:

### Step 1: Write the equations in matrix form
The given equations are:
1. \( x - y + z = 4 \)
2. \( 2x + y - 3z = 0 \)
3. \( x + y + z = 2 \)
