In 12 years, she will be x + 12 years old.

six years ago, she was x - 6 years old.

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
