Solve three types of equations with complete step-by-step solutions. Linear equations (ax + b = c): enter three coefficients and see the exact solution with working shown. Quadratic equations (ax² + bx + c = 0): enter three coefficients to get the discriminant, both real or complex roots, the vertex, and the nature of the roots. System of two equations: enter the four coefficients and two constants, then see the solution via Cramer's rule with the determinant calculation shown. Clear error messages for edge cases: zero leading coefficient, negative discriminant (complex roots), and singular systems (no unique solution). Ideal for algebra students and anyone checking their work.
