Absolute Value Equation Solver
Absolute Value Equation Solver: calculate results from explicit inputs, with a formula and worked example.
Formula
- Use the units shown beside each field.
- Results update automatically whenever you change an input.
- Displayed values use up to four decimal places, or scientific notation for very small or large numbers. Calculations use standard floating-point arithmetic; exact integer and fraction tools identify their own precision rules.
- Real finite inputs. Numeric results use floating-point arithmetic; this is not a symbolic computer algebra system.
Example Calculation
- a in |ax+b|=c: 2
- b: -4
- c: 6
|2x−4|=6 gives x=−1 or x=5.
Frequently asked questions
How do I use this calculator?
Enter a in |ax+b|=c, b, c. The result updates automatically. Use Reset to restore the example values.
What method does it use?
For c≥0 solve ax+b=c and ax+b=−c; c<0 has no real solutions.. Real finite inputs. Numeric results use floating-point arithmetic; this is not a symbolic computer algebra system.
Why might a rounded result differ?
The calculation keeps full numeric precision internally, then rounds the displayed result. Rounding intermediate steps by hand can produce a slightly different answer.
Are my inputs saved online?
No. This calculator processes your inputs in your browser. A recently used list stores only calculator names on this device, not your entered values.
