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.
