The difference in the age between Seth and Valen remains unchanged.
Valen's current age = 1 u
Seth's current age = 1 u + 11
Combined age of Seth and Johny 9 years ago
= 1 u + 1 u + 11
= 2 u + 11
2 u + 11 = 59
2 u = 59 - 11
2 u = 48
1 u = 48 ÷ 2 = 24
Seth's current age
= 1 u + 20
= 24 + 20
= 44
Answer(s): 44
