Given $A = \begin{bmatrix} -4 & 4 & 4 \\ -7 & 1 & 3 \\ 5 & -3 & -1 \end{bmatrix}, \quad B = \begin{bmatrix} 1 & -1 & 1 \\ 1 & -2 & -2 \\ 2 & 1 & 3 \end{bmatrix}$ find $AB$ . Hence, solve the system of linear equations: $x - y + z = 4,$ $x - 2y - 2z = 9,$ $2x + y + 3z = 1.$

If $A = \begin{bmatrix} 1 & 2 & 0 \\ -2 & -1 & -2 \\ 0 & -1 & 1 \end{bmatrix}$ then find $A^{-1}$ . Hence, solve the system of linear equations: $x - 2y = 10,$ $2x - y - z = 8,$ $-2y + z = 7.$

Assertion (A): $A = \text{diag} [3, 5, 2]$ is a scalar matrix of order $3 \times 3$ .
Reason (R): If a diagonal matrix has all non-zero elements equal, it is known as a scalar matrix.
