Answer:
I look at the first sentence-- the last person mentioned in the sentence is Tritt. So I use X for Tritt.
Jan's age is 3 less than twice Tritt's age===== 2x-3
then it tells us that the sum of the Tritt and Jans age is 30
the equation looks like this:
x+2x-3=30
3x-3=30
3x=33
x=11
Trit is 11
Jan is 19 2(11)-3 =22-3 19
