Question: Do 5 steps, starting from x 0 = [1 1 1] T and using 6S in the computation. Make sure that you solve each equation

Do 5 steps, starting from x0 = [1    1    1]T and using 6S in the computation. Make sure that you solve each equation for the variable that has the largest coefficient (why?). Show the details.

4x1    - x2               =  21
-x1 + 4x2      - x3    = -45
          -x2    + 4x3   =  33
