    Which of the following rearrangement make strictly diagonal dominant, the system of linear equations; x-3y+z= –2, –6x+4y+11z=1, 5x–2y–2z=9?

    5x–2y–2z=9, x–3y+z= –2, –6x+4y+11z=1

    –6x+4y+11z=1, x–3y+z= –2, 5x–2y–2z=9

    5x–2y–2z=9, –6x+4y+11z=1, x–3y+z= –2

    No need to rearrange as system is already in diagonal dominant form.
