    LU Decomposition Method, Really Need Help ASAP

    JoshMyers Copper

      Really need help with these 2 problems:

       

      Find the solution to Problems using the LU Decomposition method:

       

      1.

       

      X1 + X2 = 3

      4X1 - 2X2 = 2

       

       

       

       

      2. Find the set of equations for:

       

      X1 + 2X2 - X3 = 3.1

      -3X1 + X2 +X3 = 1.4

      -X1 - X2 + 4X3 = 7.3

       

       

       

      Thanks Guys!
