1.Using either Gaussian or Gauss-Jordan elimination, find the value(s) ofk, if any, for which the following system will have (i) no solution (ii) a unique solution, and (iii) infinitely many solutions

x + y + kz = 1

x+ky + z = 1

kx +y + z = -2

For the value ofkfor which the system has a unique solution, give unique values ofx, y,andz.

Please explain to me how to do it. thanks!
