    Matrix equation with unknown coefficents

    Supposed to solve



    I get from this following equations

    6y-2=1
    5y-2=0

    x-5=1
    x-6=0

    But there are no solutions for y!!! The book says that
    x=6 and y=1

    How?!

    You're correct, there are no solutions.

    The matrix \begin{bmatrix}-2&x\\ y&-1 \end{bmatrix} is what is wrong. It should be \begin{bmatrix}\color{red}-5&x\\ y&-1 \end{bmatrix}.
