How to use this calculator
Solve a simple linear equation in the V1 format ax + b = c without arbitrary symbolic parsing.
How the calculation works
- Enter coefficients a, b, and c.
- The calculator subtracts b from both sides.
- The result is divided by a.
Formula
x = (c - b) / a.
Example
For 2x + 4 = 10, x = 3.
Understanding your result
Use the output as a practical starting point, then review it before using it in an important workflow.
Assumptions and limitations
- a cannot be zero.
- This solver intentionally avoids free-form expression parsing.
