Solving systems of equations by elimination calculator.
When both equations of a system are in standard form \(Ax + By = C\), then a process called elimination is usually the best procedure to use to find the solution of the system. Elimination is based on two simple ideas, the first of which should be familiar. Multiplying both sides of an equation by a non-zero number does not change its solutions.
