Alvin's age is three times Elga's age. The sum of their ages is . What is Elga's age?
Answer provided by our tutors
The sum of their ages is A. (A is a constant that is not given in the question)
We assume Alvin's age is 3x and Elga's age is x
4x = A
x =A/4
So Alvin's age is 3A/4 and Elga's age is A/4. (A is a constant that is not given in the question)
