1 2-2 Solving Two-Step Equations

2 Goal: To isolate the variable How do you do this : Use Inverse Operation (Opposite) 1. do all Addition or Subtraction 2. do all Multiplication or Division Follow the Rules of Integers

3 1.2x + 3 = 15 2.5 = b – 3 2 3. 2 + 3x = 17

4 4. x – 7 = 12 3 **** Exception to the Rule 1. Multiply First to get rid of the fraction 2. Add or Subtract using inverse opertion

5 5. –x + 8 = 3 6. 6 = x – 2 4 7. -5x + 3 = -7

6 8. x + 4 = -1 3 9. 3 - x = 6 2

7 12.1/5x – 3 = 17 13.9.4 = -x + 5.6
