Solve inequalities of the form |ax + b| < c, > c, ≤ c, ≥ c
|ax + b| ? c
This calculator helps you solve absolute value inequalities of the form |ax + b| < c, |ax + b| > c, |ax + b| ≤ c, and |ax + b| ≥ c. Simply enter the coefficient a, constant b, inequality sign, and value c, and the calculator computes the solution instantly.
Input your inequality values easily:
The calculator dynamically updates the inequality formula as you type.
The calculator solves absolute value inequalities efficiently:
No manual calculation is needed – get instant and accurate results.
Understand the inequality structure:
This helps beginners learn the step-by-step reasoning behind absolute value inequalities.
Results update in real-time as you type:
1. Enter the coefficient a, constant b, inequality sign, and value c.
2. The calculator checks for valid inputs and ensures a ≠ 0.
3. For < or ≤ inequalities, it computes the interval:
−c − b / a ≤ x ≤ c − b / a
4. For > or ≥ inequalities, it computes the union of intervals:
x < min((c − b)/a, (−c − b)/a) OR x > max((c − b)/a, (−c − b)/a)
5. Input validation ensures meaningful solutions, showing "No solution" if c < 0 for < or ≤ cases.
Real-time feedback allows students to explore different coefficients and constants while learning how absolute value inequalities behave.
Suppose you have the inequality:
|2x − 3| < 5
The calculator computes:
−1.00 ≤ x ≤ 4.00
Change any coefficient, constant, or inequality sign to see instant updates and understand how solutions vary with different values.
