1. Two Step Equation 2x + 6 = 16 - 6 -6 2x = 10 2 2 x = 5

2. Multi-step Equation # 1 7x – 3x – 8 = 24 On the left side I notice that I have two like terms (7x, -3x) since the terms are alike I can combine them to get 4x. 4x – 8 = 24 +8 4x = 32 4 x = 8

3. Multistep Equation #2 5x + 3(x +4) = 28 I recognize the distributive property as 3(x +4). I must simplify that before I can do anything else 5x + 3(x +4) = 28 +3x+125x= 28 After I do the distributive property I see that I have like terms (5x and 3x) I have to combine them to get 8x before I can solve this equation

4. Multistep Equation #2 (continued) 8x + 12 = 28 I am now left with a 2-step equation Step 1: Add/Subtract The left side has +12. To undo the +12, I subtract 12 from both sides 8x + 12 = 28 -12 8x = 16 The 12 ’ s on the left cancel out leaving 8x 28 – 12 = 16

5. Multistep Equation #2 (continued) 8x = 16 Step 2: Multiply/Divide On the left side 8x means 8 times x. To undo the multiplication I divide both sides by 8 8x = 16 8 The 8 ’ s on the left cancel out leaving x 16  8 = 2 The solution that makes the statement true is x = 2 x = 2

6. Multistep Equation #3 4x – 3(x – 2) = 21 4x– 3x+ 6= 21 x = 15 x + 6 = 21 -6 -6

7. Your Turn 1.6x – 4(9 –x) = 106 2.2x + 7 = 15 3.6 = 14 – 2x 4.3(x – 2) = 18 5.12(2 – x) = 6

8. Your Turn 6. 7. 8. 9. 10. 5m – (4m – 1) = -12 55x – 3(9x + 12) = -64 9x – 5(3x – 12) = 30

9. Your Turn Solutions 1.14.2 2.4 3.4 4.8 5.1 ½ 6.3 7.-52 8.-13 9.-1 10.5
