Ethan was z years old 10 years ago
So, Ethan's PRESENT age = z + 10
How old was he (Ethan) 3 years ago?
Ethan's age 3 years ago = Ethan's PRESENT age - 3
= z + 10 - 3
= z + 7
Answer: D

Ethan was z years old 10 years ago
So, Ethan's PRESENT age = x + 10
How old was he (Ethan) 3 years ago?
Ethan's age 3 years ago = Ethan's PRESENT age - 3
= x + 10 - 3
= x + 7
Answer: D
Please change x + 7 to z + 7.
