How Gauss-Jordan Elimination Works

Gauss-Jordan elimination is a method for solving systems of linear equations by:

  1. Converting the augmented matrix to reduced row echelon form (RREF)
  2. Using elementary row operations:
    • Swap rows
    • Multiply a row by a non-zero scalar
    • Add a multiple of one row to another

A matrix is in RREF when:

  • All zero rows are at the bottom
  • The leading coefficient of each non-zero row is 1
  • The leading coefficient is the only non-zero entry in its column
  • Leading coefficients move to the right as you go down the rows

Types of Solutions:

  • Unique Solution: One solution exists
  • No Solution: System is inconsistent
  • Infinite Solutions: System has free variables
