Back Substitution Gaussian Elimination Examples

This systematic procedure transforms a matrix into row echelon form using elementary row operations, providing a clear pathway to the solution. Gaussian elimination remains a foundational algorithm in linear algebra, serving as the primary method for solving systems of linear equations.

Back Substitution Gaussian Elimination Examples

The goal is to create zeros below each leading coefficient, known as the pivot, moving from the top left to the bottom right. Dividing the second row by -3 simplifies the pivot to 1, resulting in the matrix [[2, 1, 5], [0, 1, 1].

The augmented matrix begins as [[2, 1, 5], [1, -1, 1]]. First, rows can be swapped to position a non-zero element as the pivot.

Back Substitution Gaussian Elimination Examples

To eliminate the x term in the second row, we replace the second row with two times the second row subtracted from the first row. The resulting upper triangular matrix is then solved using back-substitution, revealing the solution set where x, y, and z each equal 2.
