Given A = $\begin{bmatrix} 2 & -3 \end{bmatrix}, B = \begin{bmatrix} 0 & 2 \end{bmatrix} \text{ and C} = \begin{bmatrix} -1 & 4 \end{bmatrix};$ find the matrix X in each of the following :

(i) X + B = C - A

(ii) A - X = B + C

Given A = $\begin{bmatrix} -1 & 0 \ 2 & -4 \end{bmatrix} \text{ and } B = \begin{bmatrix} 3 & -3 \ -2 & 0 \end{bmatrix}$; find the matrix X in each of the following :

(i) A + X = B

(ii) A - X = B

(iii) X - B = A

If A = $\begin{bmatrix$}[r] -3 & -7 \ 0 & -8 \end{bmatrix}\text{ and } A - B = \begin{bmatrix}[r] 6 & 4 \ -3 & 0 \end{bmatrix}, then matrix B is :

1. $\begin{bmatrix$}[r] 9 & 11 \ -3 & 18 \end{bmatrix}

2. $\begin{bmatrix$}[r] -9 & -11 \ 3 & 8 \end{bmatrix}

3. $\begin{bmatrix$}[r] 9 & -11 \ -3 & 8 \end{bmatrix}

4. $\begin{bmatrix$}[r] -9 & -11 \ -3 & -8 \end{bmatrix}

If I is a unit matrix of order 2 and M + 4I = $\begin{bmatrix$}[r] 8 & -3 \ 4 & 2 \end{bmatrix}, then matrix M is :

2. $\begin{bmatrix$}[r] 4 & 3 \ 4 & 2 \end{bmatrix}

3. $\begin{bmatrix$}[r] 4 & -3 \ -4 & 2 \end{bmatrix}

4. $\begin{bmatrix$}[r] 4 & -3 \ 4 & -2 \end{bmatrix}
