IF you need to solve large systems with more than three variables which method is more efficient and why?

For systems with more than three equations, Gaussian elimination is far more efficient.
By using Gaussian elimination we bring the augmented matrix into row-echelon form without continuing all the way to the reduced row-echelon form. When this is done, the corresponding system can be solved by the back-substitution technique.
