These types of problems are all about recognizing key words. The word IS means EQUALS.
Eya is 3 times Bill's age but 5 less than that.
E = 3B - 5
If Eya is 28 now,
28 = 3B - 5
Add 5,
33 = 3B
Divide by 3 as a final step to solve for Bill's age.

Eya is 28 years old, so if she is 5 years younger than 3 times Bill's age, she is 79.
