How to Calculate System of Equations

Solve 2×2 systems of equations by substitution or elimination.

The Formula

Gaussian elimination

The system of equations formula uses the mathematical relationship: Gaussian elimination. Each variable in the formula represents a measurable quantity that affects the final result.

Step-by-Step Method

  1. 1Identify all input values needed for the system of equations calculation.
  2. 2Substitute your known values into the formula: Gaussian elimination.
  3. 3Perform the arithmetic operations in the correct order (PEMDAS/BODMAS).
  4. 4Check that your result has the correct units and is within a reasonable range.
  5. 5Verify using the interactive System of Equations Calculator to confirm your answer.
