  1. Lesson 11 Equations

  2. Complete the problems below. Use the handout to write your answers. Show your work!

  3. Remember: You want to get the variable on one side of the =. Remember to “do the opposite” and “undo” the operation(s). Take your time and double check your work.

  4. Questions: • Explain how you would solve: 15 = x – 2 2. To solve x – 4 = 8, what operation must be undone? 3. To solve 3x – 2 = 7, what operations must be done? Explain each step.

  5. 4. X + 13 = 40 5. 14 = x + 8 6. 8 = x – 9 7. X – 3 = 12 8. 15 = x – 2 9. 2x = 14 10. 15 = 5x 11. X – 6 = 18 12. 2x – 7 = 9 13. 25 = 5x + 10 14. 4 + 3x = 28 Solve:

  6. 15. 4a + 5 = 13 16. 23 = 7 + 5c 17. 14 = 2x – 18 18. Steve’s parents told him he could order $250 worth of school clothes from a certain catalog.
