How to Solve Linear Equations

Learn methods for solving simple linear equations like ax + b = c.

๐Ÿ“ Step by Step

  1. 1 Identify the variable (usually x) and all numbers in the equation.
  2. 2 Use inverse operations to isolate the variable. If a number is added, subtract it from both sides.
  3. 3 If the variable is multiplied by a number, divide both sides by that number.
  4. 4 Check your answer by substituting the found value back into the original equation.

Example with Solution

Example

10x
=
130
x = 13

Solution Steps

  1. 1
    Write the equation: 10x = 130
    10x
    =
    130
  2. 2
    Divide both sides by a: (10x) / 10 = 130 / 10
  3. 3
    Simplify: x = 13
    x
    =
    13
    x = 13
  4. 4
    Check: 10 ร— 13 = 130 = 130 โœ“
