x can be various numbers. To answer the questions you need to think of a number 7 or up (it can be halves, etc.):

in 12 years:        6 years ago:

x=7:  19 years old       1 year old

x=8:  20 years old       2 years old

x=9:  21 years old       3 years old

x=?:  ?+12                  ?-6

Here is how to solve it: There's a pattern... If you need any more info please message me...
