Gaussian Method of Matrix Elimination
The idea behind the problem boils down to following : You are given N linear equations and you have to calculate the sum of its solutions and then find the sum of the factors of the absolute value of the sum of its solutions.
The Idea is simple - Use the Gaussian Methods of Matrix Elimination to find the solution of the linear equations and then find the absolute value of the sum of its solutions to find the sum of its factors.
