**Jai**, Tuesday, May 22, 2012 at 7:59amlet x = age of Travis

let x-4 = age of Ellie (since Travis is four years older than Ellie)

let 2(x-4) = age of Mac (since he is twice older than Ellie)

since the sum of their ages is 44,

x + x - 4 + 2(x - 4) = 44

2x - 4 + 2x - 8 = 44

4x - 12 = 44

4x = 56

x = 14 yrs old (Travis)

x-4 = 10 yrs old (Ellie)

2(x-4) = 20 yrs old (Mac)

hope this helps~ :)
