Using matrices, solve the following system of equations: `x\ -\ y+z=4;\ 2x+y\ -\ 3z=0;\ x+y+z=2`

Explanation

To solve the system of equations using matrices and Cramer's rule, we follow these steps:

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