Problem states

Write a Python function that uses the Jacobi method to solve a system of linear equations given by Ax = b. The function should iterate 10 times, rounding each intermediate solution to four decimal places, and return the approximate solution x.

But the problem statement provides n which is the number of iterations. fix:
