Answer:

\left[\begin{array}{ccc}9\\10\\\end{array}\right]

Step-by-step explanation:

Multiply the elements in a by 3 to obtain 3a

Then add corresponding elements in both matrices for 3a + b , that is

3\left[\begin{array}{ccc}2\\4\\\end{array}\right] + \left[\begin{array}{ccc}3\\-2\\\end{array}\right]

= \left[\begin{array}{ccc}6\\12\\\end{array}\right] + \left[\begin{array}{ccc}3\\-2\\\end{array}\right]

= \left[\begin{array}{ccc}6+3\\12-2\\\end{array}\right]

= \left[\begin{array}{ccc}9\\10\\\end{array}\right]
