1. Solve the following system
2x1 — бх2 — Xз —D —38
-3x1 - x2 + 7x3 = 34
-8x1 + x2 – 2x3 = 20
using the Jacobi Method until the approximate error
is less than 0.5% with the first approximations as
x1 = -2, x2 = 4 , x3 = 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?
