An Equation Solver is an online math tool that helps you solve algebra equations quickly and accurately. This free equation solver can solve linear equations, quadratic equations, and systems of two equations. It also shows step-by-step explanations so students can understand how the answer is calculated.

Equations are used in algebra, science, engineering, finance, physics, and everyday problem solving. Instead of solving manually every time, you can enter equation values and get instant results with formulas and steps.

What is an Equation Solver?

An Equation Solver is a calculator that finds the unknown value in an equation. For example, in a linear equation like ax + b = 0, the solver finds the value of x. In a quadratic equation like ax² + bx + c = 0, it finds one or two possible values of x.

Supported Equation Types

Linear Equation Solver

A linear equation has the form ax + b = 0. The solution is x = -b/a.

Quadratic Equation Solver

A quadratic equation has the form ax² + bx + c = 0. This calculator uses the quadratic formula and discriminant to find the roots.

System of Equations Solver

A system of two equations has two unknowns, usually x and y. This solver uses determinant method to find both values.
