Answer:

[tex]X = \left[\begin{array}{cccc}12&-24&8&16\end{array}\right][/tex]

Step-by-step explanation:

A matrix is given by

[tex]A = \left[\begin{array}{cccc}6&-12&4&8\end{array}\right][/tex]

Now, we have to find the matrix X if [tex]\frac{1}{2} X = A[/tex]

⇒ X = 2A

Now, multiplication of a constant with a matrix means multiplication with that constant with all the terms of the matrix.

So, [tex]X = \left[\begin{array}{cccc}6 \times 2&-12 \times 2&4 \times 2&8 \times 2\end{array}\right][/tex]

[tex]X = \left[\begin{array}{cccc}12&-24&8&16\end{array}\right][/tex] (Answer)
