Let Tory’s sister age = x
Since Tory is 3 years older than her sister ,
Tory = (x + 3)
let Quentin’s brother age = x
( because quentin’s brother & tory’s sister are the same age , we can let both their ages be x )
Since Quentin is 8 years less than twice his brother’s age ,
Quentin = (2x -8)
Since Quentin and Tory are the same age ,
x + 3 = 2x - 8
-x = -8-3
x = 11
Ans : 11 years old :)
