The above answer is incorrect. Sorry, Amalm, but the mother was
YOUNGER THAN 66 before 1996, when Adam was one-third of her age.
In 1996 Adam was 26 years old and his mother was 66 years old.
In what year was Adam exactly one-third of his mothers age.
Let x be the number of years before 1996 that he was one-thid of
his mother's age.
Then x years before 1996, Adam was 26-x
Also x years before 1996, his mother was 66-x
So
Solve that for x, beginning by multiplying both sides by 3 to
clear the fraction. That value of x will be the number of
years before 1996 that he was one-third of his mother's age.
Then subtract that number of years from 1996 to find what year
that was.
