Answer 1

$2 *\left[\begin{array}{ccc}4&7&2\end{array}\right] + (\left[\begin{array}{ccc}6\\5\\1\end{array}\right])^t \\ \\ \left[\begin{array}{ccc}8&14&4\end{array}\right]+\left[\begin{array}{ccc}6&5&1\end{array}\right]=\left[\begin{array}{ccc}14&19&5\end{array}\right]$

Answer 2

x = 2A + $B^{t}$

2A = 2 [4   7   2]
      = [8   14    4]

$B^{t}$ = [6   5   1]

x = [8   14   4] + [6    5    1]
   = [8+6     14+5     4+1]
   = [14     19     5]
