Linear Equation Formula

A linear equation is an algebraic equation of the form ax + b = 0, where x is the variable.

x = -b / a

Example 1

Equation: 2x + 6 = 0

  • a = 2, b = 6
  • Calculation: x = -6 / 2
  • x = -3

Example 2

Equation: 5x - 10 = 0

  • a = 5, b = -10
  • Calculation: x = -(-10) / 5 = 10 / 5
  • x = 2

How to Use

  • Enter coefficient a.
  • Enter constant b.
  • Get the value of x.
