Formula and methodology
Formula: x = -b / a.
Isolate x by moving the constant across the equals sign and dividing by the coefficient. A zero coefficient is rejected instead of dividing by zero.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Coefficient a — Must be nonzero; a = 0 is not a linear equation.; minimum -1000000000; maximum 1000000000
- Constant b — minimum -1000000000; maximum 1000000000
Worked example
| Input | Value |
|---|---|
| Coefficient a | 2 |
| Constant b | -4 |
x = 2
Assumptions and limits
- a is nonzero.
- Real-number solution only.
- Inputs are finite decimals.
