SUMMARY
This discussion focuses on formally proving that elementary row operations in Gaussian Elimination do not alter the solution set of a system of linear equations. The three types of elementary row operations—permuting equations, multiplying an equation by a constant, and adding a multiple of one equation to another—are established as valid transformations that maintain the solution set. The proof relies on the inherent properties of equality and linear combinations, confirming that these operations preserve the equivalence of the original system of equations.
