Thread: Matrix question

Hi there, I was asked the following question:

The matrix:

has no solutions.

Find the value of k.

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

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

It's not the matrix, but the system of equations , that has no solution when k = –4. But yes, k = –4 is when the inconsistency occurs.
