What value satisfies this equation?
Last updated September 6, 2026
This section solves the equation types taught in a first algebra course, each with the complete working shown, not just the answer. The Linear Equation Solver handles ax + b = c, returning the value of x or a clear "no solution" / "infinitely many solutions" result. The Quadratic Equation Solver applies the quadratic formula to ax² + bx + c = 0, computing the discriminant first and returning two real, one repeated, or two complex roots. The System of Equations Solver takes two linear equations in x and y and solves them with Cramer's Rule, showing the determinants.
Each solver identifies which case applies from your coefficients, so you do not have to know in advance whether an equation factors or a system is consistent. All three run client-side and narrate every step.
