How it works
Solve a 2×2 linear system of equations using Cramer's rule.
Who it's for: Algebra students and engineers working with simultaneous linear equations.
Accepts coefficients for two equations: a₁x + b₁y = c₁ and a₂x + b₂y = c₂.
Computes the determinant and solutions x and y.
Reports when the system has no unique solution (det ≈ 0).
How to use
- Enter a₁, b₁, c₁ for the first equation.
- Enter a₂, b₂, c₂ for the second equation.
- Check det — if near zero, the system is singular.
- Read x and y as the solution pair.
