For what values of the constant k does the following system have a unique solution?Also find the solution. What is the case if k does not take on this value?
2x+4z=6,3x+y+z=-1,2y-z=-2,x-y+kz=-5
I have snapped the solution and attached the pic. Not sure how to write matrices here, that is why I wrote on a paper and snapped it.
Please let me know if it is not clear.
Only first two pictures are the unique ones, the rest are their duplicates, I uploaded them more than once by mistake. I tried removing it, but I could not. I am sorry.
