Hi there, I was asked the following question:

I got k = -4 as that's when inconsistency occurs.The matrix:

$\displaystyle \begin{bmatrix} 1 & 1 & 2 \\3 & 2 & -2\\2 & 1 & k \end{bmatrix}$$\displaystyle \begin{bmatrix} 4 \\1\\2\end{bmatrix}$

has no solutions.

Find the value of k.

Could you give it a bash and tell me what you get for it please? I'm a little unsure of it.

Thanks a lot
