MathematicsIf 5408×M=12−5 , then order of the matrix M is

If $[\begin{matrix} 5 & 4 \\ 0 & 8 \end{matrix}] \times M = [\begin{array}{l} 12 \\ - 5 \end{array}]$ , then order of the matrix M is

$[\begin{matrix} 5 & 4 \\ 0 & 8 \end{matrix}] \times M = [\begin{array}{l} 12 \\ - 5 \end{array}]$

$2 \times 2 m \times n = 2 \times 1$

$m = 1, n = 1$

Order of M is $2 \times 1$
