    The pair of linear equations \[x=y\] and \[\text{x}+\text{y}=0\]has:

    A) no common solution

    B) infinitely many solutions

    C) unique solution

    D) None of these

    Correct Answer: C

    Solution :

    [c] Equations are \[x-y=0,\,\,\,\,\,x+y=0.\]
    \[\frac{1}{1}\ne \frac{-1}{1}\]
    \[\therefore \] unique solution.
