Jackson is 6 years older than 3 times the age of his nephew. Jackson is 30 years old. How old is his nephew? Choose the steps that show how to solve this problem using arithmetic. A. Start with Jackson’s age: 30. Add 6: 30 + 6 = 36. Divide by 3: 36 ÷ 3 = 12. So, Jackson’s nephew is 12 years old. B. Start with Jackson’s age: 30. Subtract 6: 30 – 6 = 24. Divide by 3: 24 ÷ 3 = 8. So, Jackson’s nephew is 8 years old. C. Start with Jackson’s age: 30. Divide by 3: 30 ÷ 3 = 10. Add 6: 10 + 6 = 16. So, Jackson’s nephew is 16 years old. D. Start with Jackson’s age: 30. Divide by 3: 30 ÷ 3 = 10. Subtract 6: 10 – 6 = 4. So, Jackson’s nephew is 4 years old.

The easiest way to do this is by doing an inverse operation. To find Jackson’s age from his nephew’s age, you would need to add 6 and then times by 3. So if you take 6 from 30 (which gets you to 24) and divide that by 3, you get 8. A formula for this, where his nephew’s age is n, would be 3n+6=30
