Alvin's age is three times Elga's age The sum of their ages is 76 What is Elga's age?

Let's represent Elga's age as x. Since Alvin's age is three times Elga's age, we can represent Alvin's age as 3x. The sum of their ages is 76, so we can create an equation: x + 3x = 76. Combining like terms, we get 4x = 76. Dividing both sides by 4, we find x = 19. Therefore, Elga's age is 19 years old.
