Alvin is 8 years older than Elga. The sum of their ages is 78. What is Elga's age?

35

Step-by-step explanation:

ok let's look at these old farts.

alvin is 8 years older than elga, so elga needs 8 more years to be as old as Alvin is. AKA,

Alvin = Elga + 8

The sum of their ages is 78.

Alvin + Elga = 78

Now put the equations together,

(Elga + 8) + Elga = 78

2 * Elga = 70

Elga = 35

Therefore, Elga is 35 years old! So old !!
