What It Can Solve
x
One-Variable Equations
Solve 3x + 5 = 20, with brackets and x on both sides.
½
Fractions and Decimals
Handle x/3 + 2 = 5 and 0.5x + 0.25 = 1.
x, y
Two Equations
Solve pairs such as x + y = 5 and x − y = 1.
Worked Example: 3x + 5 = 20
- Subtract 5 from both sides: 3x = 15
- Divide both sides by 3: x = 5
- Check: 3 × 5 + 5 = 20 ✓

Frequently Asked Questions
Is the Linear Equation Solver free?
Yes. It is free and needs no sign-up.
What is a linear equation?
An equation where x is only to the first power, such as 2x + 3 = 11. Its graph is a straight line.
How do I type fractions and brackets?
Use / for division and brackets for groups, such as (x + 1)/2 = 4.
How do I enter two equations?
Type both with a semicolon between them, such as x + y = 5; x – y = 1.
What if my equation has x squared?
Use the Quadratic Equation Solver. This page only solves equations that are linear.
