What values of x, y and z satisfy the following system of linear equations?

$$\begin{bmatrix} 1 &2 &3 \\ 1& 3 &4 \\ 2& 2 &3 \end{bmatrix} \begin{bmatrix} x\\y \\ z \end{bmatrix} = \begin{bmatrix} 6\\8 \\ 12 \end{bmatrix}$$

  1. x = 6, y = 3, z = 2
  2. x = 12, y = 3, z = - 4
  3. x = 6, y = 6, z = - 4
  4. x = 12, y = - 3, z = 0
