Answer:
8
Step-by-step explanation:
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
