Final answer:
The student is asking to solve a system of linear equations using the Gauss-Seidel method, and we are to iterate until the relative error falls below a specified threshold. However, due to inconsistencies in the provided information, a step-by-step solution is not presented.
Step-by-step explanation:
The problem at hand requires us to use the Gauss-Seidel method to solve a system of linear equations with a stopping criterion related to the percent relative error. Given that we have inconsistencies in the provided equations and limited context for the SEO references, we will not be able to present a full Gauss-Seidel iterative process for the original system provided. The general approach, however, would involve rearranging each equation to solve for one variable in terms of the others, then iteratively updating values for each variable using previous estimates, and checking for convergence based on a pre-determined relative error threshold.
