The problem description might not be written correctly for the given total age of 18 years.

If Katie were "five times as old as" sal, then this would mean,
Katie is 5A and sal is A.
5A%2BA=18
6A=18
A=3----------"sal a" would be 3 years old, now.

Continuing this way, Katie NOW, is 15 years old and "sal a", 3 years old;
In x years:
18%2Bx=2%283%2Bx%29
18%2Bx=6%2B2x
12=x----------In 12 years, Katie is two times "sal a" age.

That would make Katie aged 30 and "sal a" aged 15.
