    Determine the value of k such that the system is consistent.

    Determine the value of k such that the system of linear equations is consistent.

    kx+y=0
    x+ky=1

    My test is Thursday and tutors at school couldn't help, neither will teacher. Thank you!

    Using the determinate find the values of k such that
    \left| {\begin{array}{*{20}c}   k & 1  \\   1 & k  \\ \end{array} } \right| \ne 0

    Can you please explain step-by-step? I know what a determinant is, but don't understand how I use it in this problem to solve.

    Please understand that this is not a homework service nor is it a tutorial service. There is clearly some kind of misunderstand going on here.
    You posted this in a linear algebra forum. Determinants are part of any linear algebra course. Have you looked in your lector notes or text material?
    You can also use recourses from the web.
