Alright so let's make Jan's age "J" and Trits' age "T" Jan's age is 3 years less than twice trits age: 2T-3=J The sum of their ages is 30: J+T=30 We can plug the first equation into the second: 2T-3+T=30 3T-3=30 3T=33 T=11 So Trits' age is 11, and we can plug 11 for T for either equation 2(11)-3=J 19=J Jan is 19 and Trit is 11 :)
