Problems On Solving Linear System

Problems on Solving Linear System-1:

Putting x = x1, y = y0 in equation above, we have

   

 

Second Iteration,

Putting y = y1, z = z1 in the above equations, we get

  

Puttingx = x2, z = z1 in above equations, we obtain

  

Putting x = x2, y = y2 in above equations, we get

  

 

In Third Iteration,

We get

The values in the second and third iterations being practically the same, we can stop. Hence the solution is

            x = 1, y = −1, z = 1.
