How to Solve a Linear Equation
Formula
Given ax + b = c, solve for x:
x = (c - b) / a
1. Subtract b from both sides: ax = c - b 2. Divide both sides by a: x = (c - b) / a
This works for any linear equation with a single unknown, as long as a is not zero.
Example Calculation
Solve 3x + 7 = 22.
- 013x + 7 = 22
- 023x = 22 - 7 = 15
- 03x = 15 / 3 = 5
