Ann is 4 years older than Toby.
Bill is twice Toby's age
if the sum of their ages is 28, how old is Ann ?
~~~~~~~~~~~~
Let x be Ann age.
Then the Toby's age is (x-4) years and Bill is 2(x-4) yearts old.
The sum is 28 years
x + (x-4) + 2(x-4) = 28
(x-4) + (x-4) + 2(x-4) = 28-4
4(x-4) = 24
x-4 = 24/4 = 6
x = 6 + 4 = 10.
ANSWER. Ann is 10 years old.
