## Quick Answer

Solve simultaneous linear equations. Enter your equations with two or three variables to find the unique solution with step-by-step work.

## Definition

A system of equations calculator is an algebraic tool that solves sets of simultaneous equations with multiple variables. The calculator supports systems of two or three linear equations, using methods such as substitution, elimination, matrix inversion, or Cramer's rule to find the variables' values. It can identify unique solutions, infinitely many solutions, or inconsistent systems with no solution, and displays the step-by-step mathematical work for the selected resolution method. Students and engineers use this tool to solve linear algebra problems.

## How to Use

1. **Select number of variables** — Choose whether you are solving a system with two variables or three variables.
2. **Input the equations** — Type the coefficients and constants of your equations in the fields.
3. **Read the solution** — View the values of variables X, Y, and Z along with the step-by-step solution.
