Simultaneous Equations Solver
Solve a system of two linear equations in two variables.
Result
Results are estimates for general information only and are not professional advice.
Solving two equations
Two linear equations in x and y can be solved together to find the single point where they meet. This solver uses Cramer's rule (determinants) to return the exact values of x and y, or tells you if there is no unique solution.
Frequently Asked Questions
What is the Simultaneous Equations Solver?
Solve a system of two linear equations in two variables. It runs instantly in your browser and is completely free to use.
What do I need to enter to use the Simultaneous Equations Solver?
The Simultaneous Equations Solver asks for the following values (6): a₁ (x in eq 1), b₁ (y in eq 1), c₁ (eq 1 =), a₂ (x in eq 2), b₂ (y in eq 2), c₂ (eq 2 =). Fill them in and the result appears immediately — the calculation runs on your own device, so nothing you type is sent to a server.
How accurate is the Simultaneous Equations Solver?
The Simultaneous Equations Solver uses standard, widely-accepted formulas, so its figures are reliable estimates for everyday planning. They are not a substitute for advice from a qualified professional.
Is the Simultaneous Equations Solver free, and do I need an account?
Yes. The Simultaneous Equations Solver — and every other calculator on Calculatis — is completely free, with no registration, no download and no limit on how often you use it.
