Question

Alvin is 15 younger than elga the sum of their age is 27 what is elga age

Answer 1

27 years old

Explanation:

Let Alvin's age be x and Elga's age is y:

y - x = 15

x + y = 27

2y = 42 (use elimination method)

y = 21

x = 6 (plug it back into either equation)

Therefore Alvin is 6 and Elga is 27
