Stuck again, please help.

Sean is 3 years older than Wayne. The sum of their ages is 15. How old is Sean?
The answer is S=9 W=6
Let the age of Wayne be x years.
Let the age of Sean be x + 3 years.
Therefore:
x + x + 3 = 15
2x + 3 = 15
2x + 3 - 3 = 15 - 3
2x = 12
x = 6
x + 3 = 6 + 3 = 9
Therefore:
Wayne is 6 years old and
Sean is 9 years old.
