The difference in the age between Sean and Eric remains unchanged.
Eric's current age = 1 u
Sean's current age = 1 u + 8
Combined age of Sean and Johny 14 years ago
= 1 u + 1 u + 8
= 2 u + 8
2 u + 8 = 66
2 u = 66 - 8
2 u = 58
1 u = 58 ÷ 2 = 29
Eric's current age
= 1 u + 14
= 29 + 14
= 43
Answer(s): 43
