    M = \left[\begin{matrix}a&b&c\\d&e&f\\g&h&j\end{matrix}\righ  t].

    You know M\mathbf{p} = \mathbf{q}, M\mathbf{q} = -2\mathbf{r}, M\mathbf{r} = 2\mathbf{p}+ 4\mathbf{q}.


    So perform these multiplications to give you a set of equations to solve for a,b,c,d,e,f,g,h,j.

    As a simple courtesy to the people you are asking for help, please type out questions like this rather than attaching a file. It doesn't take much time and shows you are willing to make some small effort in order to get help.

    On the contrary, i thought it would be easier and clearer if i attached it as a file.. i'll make sure to type it out next time.

    If you are willing to help...I managed to find Matrix M as ( -1 3 1 )
    0 4 2
    1 -1 1

    However for the second part M-1p i keep getting ( 1 ) .. which is wrong..
    -5/8
