4. StepsVideoExamplesQuiz Home: References Steps for solving equations with the variable on both sides Step 4: Solve for variable (Multiply or Divide to solve for the variable) Step 3: Isolate the variable (move the constant terms to opposite side of the variable) Step 2: Move the variable to one side (the side with the bigger coefficient ) Step 1: Simplify Equation (Use Distributive Property and Combine Like Terms)

6. StepsVideoExamplesQuiz Home: References Choose one of the following examples: Example 1: 2x + 5 = 4x – 7 Example 2: 3 (x + 2) = -2x – 9

7. StepsVideoExamplesQuiz Home: References Example 2 Example 1: 2x + 5 = 4x – 7 Step 1 (Simplify): No need to simplify since already in simplest terms Step 2 (Move Variable to one side): We will move the variable to the right since 4x is bigger than 2x: 2x + 5 = 4x – 7. -2x -2x. 5 = 2x – 7 Step 3 (Move constant terms):. +7 +7. 12 = 2x Step 4 (Solve for Variable):. ÷ 2 ÷2. 6 = x Thus the answer is x = 6

StepsVideoExamplesQuiz Home: References Example 1 Example 2: 3 (x + 2) = -2x – 9 Step 1 (Simplify): Step 2 (Move Variable to one side): Step 3 (Move constant terms): Step 4 (Solve for Variable): Thus the answer is x = -3 3 (x + 2) = -2x – 9 3x + 6 = -2x – 9.+2x +2x. 5x + 6 = -9. - 6 - 6. 5x = -15. ÷ 5 ÷ 5. x = -3
