The difference in the age between Rael and Bobby remains unchanged.
Bobby's current age = 1 u
Rael's current age = 1 u + 12
Combined age of Rael and Johny 14 years ago
= 1 u + 1 u + 12
= 2 u + 12
2 u + 12 = 58
2 u = 58 - 12
2 u = 46
1 u = 46 ÷ 2 = 23
Bobby's current age
= 1 u + 14
= 23 + 14
= 37
Answer(s): 37
