System of Equations Solver
Enter finite coefficients for a small linear system and inspect its numerical result.
System of Equations Solver
Coefficients
Enter finite decimal coefficients. Results use JavaScript floating-point arithmetic; near-singular systems use a relative tolerance and may need exact arithmetic for confirmation.
Result
A QUICK WALKTHROUGH
How to use this tool
- Choose 2×2 or 3×3.
- Enter coefficient and right-hand-side values.
- Solve and review determinant and the unique, infinite, or no-solution classification.
Small systems only
The tool accepts 2×2 and 3×3 linear systems and uses determinant-based floating-point arithmetic locally.
Classification and precision
Rank comparison reports unique, infinitely many, or no solution using a relative tolerance. Near-singular results are numerical indications, not a proof of exact symbolic behavior.
GOOD TO KNOW
Common questions
Does it support nonlinear equations?
No. It solves only linear 2×2 and 3×3 systems.
Are results exact?
No. Decimal inputs use browser floating-point arithmetic and displayed values are limited precision.
