Question

Hello, please answer item number 2. Thank you

1. Solve the following system
2x1 – 6x2 – T3 = -38
-3x1 – 22 + 7x3 = 34
-8x1 + x2 – 2x3 = 20
using the Jacobi Method until the approximate error is less than 0.5% with the first approximations as
æ1 = -2, x2 = 4, æ3 = 3
Round-off intermediate values to 6 decimal places and the answer to 4 decimal places.
How many iterations were made to solve the system?
