About this Tool
Enter a linear equation such as 3x + 7 = 22 to solve it for the unknown variable. The solver simplifies both sides, combines equivalent terms and shows the transformations used to isolate the variable. It can also identify equations with no solution or infinitely many solutions. All calculations run locally in your browser.
Examples
- 3x + 7 = 22
- 5(x - 2) = 3x + 8
- 4 - 2x = 3x + 19
- 2(x + 3) - 4 = 10
- 7x - 5 = 7x + 2
Frequently Asked Questions
What types of equations can this solver handle?
It is designed for linear equations with one unknown variable. It can handle parentheses, negative values, decimal numbers, fractions and variables appearing on both sides of the equation.
Does the equation solver show calculation steps?
Yes. The solver shows how expressions are expanded and simplified, how variable and constant terms are collected and how the variable is isolated.
Can an equation have no solution?
Yes. If simplification produces a false statement such as 0 = 7, the equation has no solution because no value of the variable can satisfy it.
When does an equation have infinitely many solutions?
An equation has infinitely many solutions when both sides simplify to the same expression. In that case, every permitted value of the variable satisfies the equation.
Can I enter fractions and decimal numbers?
Yes. The solver can process equations containing decimal values and fractions, provided the expression uses supported mathematical notation.
Are my equations sent to a server?
No. The equation is processed locally in your browser and is not uploaded.
