    1. The problem statement, all variables and given/known data

    Given that  
    |a b c| =-6
    |d e f|    
    |g h i|

    |-3a   -3b   -3c    |
    |d       e      f   |
    |g-4d   h-4e  i-4f  |

    2. Relevant equations


    3. The attempt at a solution

    I am not sure where to start to solve this question. I am familiar with matrix applications but not sure determine the answer.

    Thanks, in advance.
