ધારો કે $A = \begin{bmatrix} 2 & 4 \\ 3 & 2 \end{bmatrix}$,$B = \begin{bmatrix} 1 & 3 \\ -2 & 5 \end{bmatrix}$,અને $C = \begin{bmatrix} -2 & 5 \\ 3 & 4 \end{bmatrix}$ છે. $3A - C$ શોધો.

  • A
    $\begin{bmatrix} 8 & 7 \\ 6 & 2 \end{bmatrix}$
  • B
    $\begin{bmatrix} 8 & 7 \\ 6 & 3 \end{bmatrix}$
  • C
    $\begin{bmatrix} 7 & 8 \\ 6 & 2 \end{bmatrix}$
  • D
    $\begin{bmatrix} 8 & 6 \\ 7 & 2 \end{bmatrix}$
