2-2 Solving Two-Step Equations

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

1.2x + 3 = = b – x = 17

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. –x + 8 = = x – x + 3 = -7

8. x + 4 = x = 6 2

12.1/5x – 3 = = -x + 5.6
