Question

Jan's age is 3 years less than twice Tritt's age. The sum of their ages is 30. find their ages

Answer 1

let Tritt's age = t & Jan's age = 2t - 3

if the sum of their ages equals 30 then..

`t + 2t - 3 = 30`
combine terms and simplify

`3t = 27`
now simply divide

`t = 9`
and to find Jan's age just plug 9 in

`2(9) - 3`

`18 - 3 = 15`

Jan's age = 15
Tritt's age = 9
