Let's work that out together.
X + 10 = 34 so 34 - 10 = X so 34 - 10 = 24
Elga is X so is 24.

A = E - 9 A + E = 87 that is, (E - 9) + E = 87 2E - 9 = 87 2E = 87 + 9 = 96 E = 96/2 = 48

Answer: 30 (Dad) & 6 (Son) 2 years later they will be 32 & 8 which equals 40.

If Alvin is 7 years younger than Elga, then Alvin + 7 = Elga. If the sum of their ages is 87, then Alvin + Elga = 87. Substitute Alvin + 7 in the previous equation to get Alvin + (Alvin + 7) = 87. Reduce that and get 2 Alvin = 80 which means that Alvin = 40. That means that Elga = 47.
It is 50 years.
alvin is 9 years younger than elga the sum of there age is 53 how old is elga
57
Alvin +Elga = 56 3 : 1 56 รท 4 = 14 Alvin = 56 - 14 = 42 Elga = 14
Elga is 24, because this would mean that Alvin's age is 48, and 24+48=72.
A = E - 9 A + E = 87 that is, (E - 9) + E = 87 2E - 9 = 87 2E = 87 + 9 = 96 E = 96/2 = 48
Alvin is 44 and Benjamin is 11.
