Alvin is 6 years younger than elga. the sum of their ages is 92. what is elga's age?

Elga's age be 49 years

Step-by-step explanation:

Let Elga's age be x years

Then, Alvin's age will be (x - 6) years

The sum of their ages is 92

Therefore,

x + (x - 6) = 92

x + x - 6 = 92

2x - 6 = 92

2x = 92 + 6

2x =  98

x = 98 /2

x = 49 years

Hence,

Elga's age be 49 years
