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 three times Jen’s age is 66. How old is Jen?

Answer 1

This year, Jen=x, Jack = 2x-2
Now add things up as required, and solve for x, Jen's age.

Answer 2

Let x = Jack

x = 2J-2

x + 3J = 2J-2 + 3J = 66

In calculating for Jen's age, it does not come out in even years. Typos?
