    Consider the equation Ax=b, with

    a=(1 1 a)
    (1 -1 1)
    (2 -1 -1)

    ( b )
    ( b )

    for which values of a,b this system has no solutions? infinitely many solutions? unique solution? if possible, find the solution x explicitly in terms of a,b.

    [A|b] =

    So it is obvious that the system has no solution if
    -(5+a)/2 = 0 but -3-b  0, ...

    Solution Summary

    This looks at a system of equations and shows how to determine if it has no, infinitely many, or one unique solution, and then shows how to find the solution explicitly in terms of a and b.
