Pamela‘s age is two times Jerry’s age. The sum of their ages is 30 what is Jerry’s age?

Let's say Jerry's age is x.

Therefore, Pamela's age is 2x.
The sum of their ages is x + 2x = 30.
Combining like terms, we get 3x = 30.
Dividing both sides by 3, we get x = 10.
Therefore, Jerry is 10 years old.
