John will be [tex]x[/tex] years old in 7 years. How old was he last year?

A. [tex]x + 7[/tex]
B. [tex]1 - x - 7[/tex]
C. [tex]x + 8[/tex]
D. [tex]x - 8[/tex]

Right now, he is 7 less than he will be in 7 years, and 1 more than he was last year.
'x' is 7 more than he is right now, and 8 more than he was last year.
If 'x' is 8 more than he was last year, then he was (x - 8) last year.
That's Choice-'D'.

D is the answer, because seven minus X is his age this year and a year before that is last year. So the answer is X-8

John was x − 8 years old last year, as calculated from his age in 7 years. Therefore, the correct answer is option D.
