Guass Jordan Method of solving Simultaneous equations.

sorry for the error in the video it is not Guass Jacobi method it is Gauss Jordan Method.
Solve the following Simultaneous equations using Gauss Jordan Elimination Method
x+3y+3z=16
x+4y+3z=18
x+3y+4z=19
here we have to make the upper matrix and lower matrix to zero so only diagonal elements will be there.
