Linear System Solver

Solve a system of two or three linear equations with exact rational arithmetic — no floating-point rounding, so answers like 5/4 stay exact. Enter the coefficients and right-hand-side values and the solver computes the determinant, classifies the system as having a unique solution, being inconsistent (no solution), or being dependent (infinitely many solutions), and reports each variable as an exact fraction with a decimal approximation when the solution is unique. Everything runs locally in your browser.
