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

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

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!

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

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