Understanding Gaussian Elimination

What is a System of Equations?

A system of equations is a collection of two or more equations with the same set of variables. Solving a system means finding values for the variables that satisfy all equations simultaneously.

2x + 3y = 8

x - y = 1

Solution: x = 2.2, y = 1.2

The Gaussian Elimination Method

  1. Form Augmented Matrix: Write equations as a matrix
  2. Forward Elimination: Create zeros below diagonal
  3. Back Substitution: Solve from bottom to top
  4. Verify: Check solution in original equations

Row Operations

  • Swap rows: Exchange two rows
  • Multiply row: Multiply all elements by a constant
  • Add rows: Add multiple of one row to another

These operations don't change the solution!
