Gauss-Jordan Elimination Calculator

Solve a 2x2 or 3x3 linear system by reducing the augmented matrix [A|b] to reduced row echelon form (RREF) with partial pivoting.

Frequently Asked Questions

How is Gauss-Jordan elimination different from Gauss elimination?

Gauss elimination stops at row echelon form and uses back-substitution. Gauss-Jordan continues to reduced row echelon form so the variables can be read off directly.

What happens when the system has no solution?

After row reduction one row becomes 0 = nonzero, an impossibility. The system is inconsistent.

When is the solution not unique?

When a row of A becomes all zero and the matching b entry is also zero. The free variables generate an infinite family of solutions.
