Answer:
![3B - 4C = \left[\begin{array}{cc}-8 &-23\\1&-15\end{array}\right]](https://tex.z-dn.net/?f=3B%20-%204C%20%3D%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D-8%20%26-23%5C%5C1%26-15%5Cend%7Barray%7D%5Cright%5D)
Explanation:
Given
![B = \left[\begin{array}{cc}8&-5\\-1&3\end{array}\right]](https://tex.z-dn.net/?f=B%20%3D%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D8%26-5%5C%5C-1%263%5Cend%7Barray%7D%5Cright%5D)
![C = \left[\begin{array}{cc}8&2\\-1&6\end{array}\right]](https://tex.z-dn.net/?f=C%20%3D%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D8%262%5C%5C-1%266%5Cend%7Barray%7D%5Cright%5D)

Determine 3B - 4C
If
![B = \left[\begin{array}{cc}8&-5\\-1&3\end{array}\right]](https://tex.z-dn.net/?f=B%20%3D%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D8%26-5%5C%5C-1%263%5Cend%7Barray%7D%5Cright%5D)
Then
![3B = 3 * \left[\begin{array}{cc}8&-5\\-1&3\end{array}\right]](https://tex.z-dn.net/?f=3B%20%3D%203%20%2A%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D8%26-5%5C%5C-1%263%5Cend%7Barray%7D%5Cright%5D)
![3B = \left[\begin{array}{cc}24&-15\\-3&9\end{array}\right]](https://tex.z-dn.net/?f=3B%20%3D%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D24%26-15%5C%5C-3%269%5Cend%7Barray%7D%5Cright%5D)
Similarly,
If
![C = \left[\begin{array}{cc}8&2\\-1&6\end{array}\right]](https://tex.z-dn.net/?f=C%20%3D%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D8%262%5C%5C-1%266%5Cend%7Barray%7D%5Cright%5D)
Then
![4C = 4 * \left[\begin{array}{cc}8&2\\-1&6\end{array}\right]](https://tex.z-dn.net/?f=4C%20%3D%204%20%2A%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D8%262%5C%5C-1%266%5Cend%7Barray%7D%5Cright%5D)
![4C = \left[\begin{array}{cc}32&8\\-4&24\end{array}\right]](https://tex.z-dn.net/?f=4C%20%3D%20%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D32%268%5C%5C-4%2624%5Cend%7Barray%7D%5Cright%5D)
So:
![3B - 4C = \left[\begin{array}{cc}24&-15\\-3&9\end{array}\right] - \left[\begin{array}{cc}32&8\\-4&24\end{array}\right]](https://tex.z-dn.net/?f=3B%20-%204C%20%3D%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D24%26-15%5C%5C-3%269%5Cend%7Barray%7D%5Cright%5D%20-%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D32%268%5C%5C-4%2624%5Cend%7Barray%7D%5Cright%5D)
This gives:
![3B - 4C = \left[\begin{array}{cc}24 - 32 &-15-8\\-3-(-4)&9-24\end{array}\right]](https://tex.z-dn.net/?f=3B%20-%204C%20%3D%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D24%20-%2032%20%26-15-8%5C%5C-3-%28-4%29%269-24%5Cend%7Barray%7D%5Cright%5D)
![3B - 4C = \left[\begin{array}{cc}-8 &-23\\1&-15\end{array}\right]](https://tex.z-dn.net/?f=3B%20-%204C%20%3D%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D-8%20%26-23%5C%5C1%26-15%5Cend%7Barray%7D%5Cright%5D)
