3. Then/Now You have already solved two-step equations. (Lessons 4–5) Solve multi-step equations.

4. Example 1 Solve a Multi-Step Equation 8x – 5 = 27Step 1: Rewrite the equation Solve 5x + 3x – 5 = 27. x=4Step 4: Do the math 8x = 32 + 5 =+ 5 Step 2+3: Draw line; Inverse Repeat Steps 2+3

5. Example 2 Solve a Multi-Step Equation w=33Step 4: Do the math

6. Example 1 Solve a Multi-Step Equation -6c + 6= 30Step 1: Rewrite the equation Solve -4c + 6 – 2c = 30. c=-4Step 4: Do the math -6c = 24 - 6 =- 6 Step 2+3: Draw line; Inverse Repeat Steps 2+3

7. Example 1 Solve a Multi-Step Equation -4d + 3 = 19Step 1: Rewrite the equation Solve 11 – 4d – 8 = 19. d=-4Step 4: Do the math -4d = 16 - 3 = - 3 Step 2+3: Draw line; Inverse Repeat Steps 2+3

8. Example 4 Combine Like Terms Before Solving 1b – 3b + 8 =18Step 1: Rewrite the equation –2b + 8 = 18Step 1: Rewrite the equation –2b + 8 =18 – 8 – 8 Step 2+3: Draw line; Inverse –2b=10 Solve b – 3b + 8 = 18. Check your solution. Repeat Step 2+3. b = –5Step 4: Do the math Answer: The solution is –5.
