How does the Inequality Calculator work?

Solve like an equation, but flip inequality when multiplying/dividing by negative Then: 2x ≤ 10 → x ≤ 5 Then: −3x > 6 → x < −2 (flip when dividing by −3) Then: Represent solution as interval: (−∞, 5].

Can you give an example of how to use the Inequality Calculator?

Example: Input 2x ≤ 10 gives a result of x ≤ 5 (interval: (−∞, 5]).

Is the Inequality Calculator free to use?

Yes — completely free with no registration, download, or subscription required. All calculations happen instantly in your browser.

How accurate is the Inequality Calculator?

Our Inequality Calculator uses verified mathematical formulas and is accurate to multiple decimal places. Results are calculated in real-time using the same methods used by professionals.

✓Solution

x ≤ 5.0000

A linear inequality solver finds all values of x satisfying an inequality like 2x ≤ 10. Unlike equations with one solution, inequalities have a range of solutions, displayed as an interval.
