Math Help - Matrix equation with unknown coefficents

1. 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?!

2. Re: Matrix equation with unknown coefficents

You're correct, there are no solutions.

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