Result methodology

The certified engine performs deterministic Gauss–Jordan elementary row operations on the validated 2×3 matrix.

Solution steps
  1. Scale R1 by 1/1
  2. R2 ← R2 - (1)R1
  3. Scale R2 by 1/-2
  4. R1 ← R1 - (1)R2

How this calculator works

The engine identifies pivots, scales pivot rows to one and eliminates each pivot column above and below to produce RREF.

Formula

Gauss–Jordan row reduction

Reduces a 2×3 matrix to reduced row echelon form with deterministic elementary row operations.

Worked example

Augmented system is a verified test case used by the calculation engine.
