1. September 18, 2012 Solving Multi-Step Equations Warm-up: Compare HW answers and write problems you don’t understand up on the board.

2. Reviewing Solving One-Step Equations Isolating x Solve and describe each step. Then check your answer. 1. x + 16 = -13 2. 28 = x – (-13) 3. -10 = -35x4.5.

3. Lesson 2.3 Solving Multi-Step Equations So we can now solve: x – 4 = -16 And, we can solve: -2x = 16 Solve: 2x – 4 = -16 Steps to Solve Can we simplify? What side is “x” on? Add/Subtract Multiply or Divide Check your answer!

4. More examples… Example 1: 3(2x – 5) = -8 Steps to Solve Can we simplify? What side is “x” on? Add/Subtract Multiply or Divide

5. Try these and don’t forget the steps! 1.20 = 3x + 25 2. -5x – 22 = -7 3. 4. 5. -3 = 8x – 2x +15 Steps to Solve Can we simplify? What side is “x” on? Add/Subtract Multiply or Divide

6. Make a Review Sheet Pick 6 problems from your textbook, PG. 146 #22-42. Solve and check your answers. Then switch your review with another student.
