    Re: Find the inverse for the following matrix (With progess)

    You just need to apply the following operations to the matrix on p3:

    1. add 7*R3 to R1
    2. add 5*R3 to R2
    3. multiply R2 by -1

    Afterwards, the rightpart of the augmented matrix is the inverse of the original matrix.
