Moved from a technical forum, so homework template missing

I have equation system:

x + y + z - a*k = 0

-b*x + y + z = 0

-c*y + z = 0

-d*x + y = 0

where: a, b, c, d = const.

Have to find: x, y, z, k

Attempt of solution:

I create Matrix

When I try to use Cramer's rule - because of the Matrix B, I have determinant - 0.

Same Situation, if I try to inverse Matrix A and multiply with B.

Any help?
