This year, your brother jack will be 2 years from being twice as old as your sister jen. the sum
of jack's age and 3 times jen's age is 66. how old is jen?

13 years old (if you round it)

explanation:

let jenny's age be "x":

then james age is "2x-2"

the sum of james age and 3 times jennys age is 66. how old is jenny?

2x-2 + 3x = 66

5x = 68

x = 13 3/8 years
