Got another one that is also baffling me

Attachment 23008

After some simplification, I get

-x+2x=0

-x+10=1

Nope, no solutions for x!

5-5y=0

5-xy=1

Neither this one!

The book saysx=9andy=1. Help me?

As in the previous thread, the question is wrong. Either the book is full of misprints, or you are copying the questions very carelessly.

The first matrix should be $\displaystyle \begin{bmatrix}1&5\\ 2&x \end{bmatrix}$, not $\displaystyle \begin{bmatrix}1&5\\ 1&x \end{bmatrix}.$ - Dec 5th 2011, 10:37 AMSweatingBearRe: Another matrix equation with unknown coefficients
