How to Use the Inequalities Calculator
This calculator solves linear inequalities in one variable (e.g., 2x + 3 > 5) and shows the solution on a number line.
- Enter an inequality in the input field. Use the variable
x. Supported operators:<,>,≤,≥. - Examples of valid inputs:
2x + 3 > 53x - 1 ≤ 2x + 4-x + 2 < 04 ≥ x - 1
- Click "Solve" to get the solution.
- Results show:
- The simplified inequality (e.g.,
x > 1). - A number line with the solution region highlighted (arrow) and the boundary point (filled circle for ≤/≥, open circle for </>).
- Step-by-step algebraic work.
- The simplified inequality (e.g.,
Note: Only linear inequalities in x are supported. Fractions and decimals are accepted. If no variable is present, the calculator will indicate if the inequality is always true or false.

Frequently Asked Questions
It supports linear inequalities with one variable, including <, >, ≤, and ≥.
Yes, you can use decimal numbers. Fractions are not directly supported; convert to decimals.
The calculator will display 'No solution' if the inequality is impossible.
