1. The problem statement, all variables and given/known data The problem is attached. 2. Relevant equations Isolating each x_i. 3. The attempt at a solution I watched this video for the Jacobi method.: I also watched this video for the Gauss-Seidel method.: At least based on the videos mentioned above, it seems that the difference between the Gauss-Seidel method and the Jacobi method is that the Gauss-Seidel method always computes the the latest x_i, by using already-computed values from the current iteration, if available, unlike the Jacobi method which seems to just use values from the previous iteration, even if values from the current iteration are available. So, am I correct in thinking that the solution is using the Jacobi method, despite the question asking for the Gauss-Seidel method to be used? Any input would be greatly appreciated!
