1.Using either Gaussian or Gauss-Jordan elimination, find the value(s) of k, 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 of k for which the system has a unique solution, give unique values of x, y, and z.
Please explain to me how to do it. thanks! (Wink)
