Christina’s age is equal to three times her age in 3 years’ time minus three times her age 3 years ago. How old is Christina?

Answer 1

C=Christina's age today
C+3 = her age in three years time
C-3 = her age three years ago

Christina’s age (C=) is equal to three times (3*) her age in 3 years’ time (C+3) minus (-) three times (3*) her age 3 years ago (C-3).

C=3*(C+3)-3*(C-3)
Solve for C (she's still a teenager).
