    The solution of following system of linear equation is:

    2x-2y+3z=1
    5x-6y+10z=2
    2x-4y+9z=1

    x=2, y=3, z=1

    And the solution of this system is:

    2x-2y+3z=1
    5x-6y+10.1z=2
    2x-4y+9z=1

    x=2.375 y= 3.75, z= 1.25
    (You do not have to show this)

    Comparing the 2 solution can you determine whether the fist system of equations is ill-conditioned or not?? Explain why it is ill-conditioned??

    In part 1 in this question I have already found norm and the norm says it is ill-conditioned.
