let t = Tom's age
let g = Gary's age
let r = Reb's age
let s = Sam's age
:
tom is four less than twice gary's age.
t = 2g - 4
:
Gary's age
2g - 4 = t
2g = t + 4
g = %28%28t%2B4%29%29%2F2
:
rebecca is the youngest and she is two less than half gary's age after it was increased by three.
r = .5(g+3) -2
:
sam's age is the ratio of seven more than gary's age to eight less than gary's age.
s = %28%28g%2B7%29%29%2F%28%28g-8%29%29
