Solve linear equations in one or two variables with clear steps and a check. Free, with no sign-up.

Use / for division and brackets for groups. For two equations, put a semicolon between them. Try an example:

How to Use the Linear Equation Solver

Choose one variable, fractions and decimals, or two variables.

Use x, and y for two equations. Put a semicolon between two equations.

See each step, the answer and a check.

Solve 3x + 5 = 20, with brackets and x on both sides.

Handle x/3 + 2 = 5 and 0.5x + 0.25 = 1.

Solve pairs such as x + y = 5 and x − y = 1.

Yes. It is free and needs no sign-up.

An equation where x is only to the first power, such as 2x + 3 = 11. Its graph is a straight line.

Use / for division and brackets for groups, such as (x + 1)/2 = 4.

Type both with a semicolon between them, such as x + y = 5; x – y = 1.

Use the Quadratic Equation Solver. This page only solves equations that are linear.
