    • Definitions
      • Linear Equation: a mathematical expression that has an equal sign and linear expressions
      • Variable: a number that you don’t know, often represented by “x” or “y” but you can use any letter
      • Linear Expression: a mathematical statement that performs functions of addition, subtraction, multiplication, and division
        • The variable can’t have exponents, can’t multiply or divide two variables, and can’t find the variable under a square root symbol.

    • Steps to Solving a Linear Equation
      • Isolate the terms that contain the variable you wish to solve for.
      • Isolate the variable you wish to solve for.
      • Substitute your answer into the original equation and check that it works.

    • Example 1 Solve for x if 2x + 4 = 10 Steps to Solving Quit
      • Isolate “x” to one side of the equation by subtracting 4 from both sides.
      • Divide both sides by 2.
      • Check your work with the original equation.
      • 2x + 4 – 4 = 10 – 4
      • 2x = 6
      • 2x/2 = 6x/2
      • x = 3
      • 2x + 4 = 10
      • (2 * 3) + 4 = 10
      • 6 + 4 = 10
      Quit
    • Example 2 Solve for x if 3x – 4 = -10 Steps to Solving Quit
      • Isolate “x” to one side of the equation by adding 4 to both sides.
      • Divide both sides by 3.
      • Check your work in the original equation.
      • 3x – 4 + 4 = -10 + 4
      • 3x = -6
      • 3x/3 = -6/3
      • x = -2
      • (3 * -2) – 4 = -10
      • -6 – 4 = -10

      Answer Answer Quit
    • Answer to Practice Problem 1
      • Isolate “x” to one side of the equation by adding 4 to each side.
      • Divide both sides by 4.
      • Check your work in your original equation.
      • 4x – 4 + 4 = 8 + 4
      • 4x = 12
      • 4x/4 = 12/4
      • x = 3
      • (4 * 3) – 4 = 8
      • 12 – 4 = 8
      4x – 4 = 8 Quit Back to Practice Problems
    • Answer to Practice Problem 2
      • Square the number.
      • Subtract both sides by 9.
      • Check your work in the original equation.
      • x + 3^2 = 12
      • x + 9 = 12
      • x + 9 – 9 = 12 - 9
      • x = 3
      • 3 + 3^2 = 12
      • 3 + 9 = 12
      x + 3^2 = 9 Quit Back to Practice Problems
