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).
C+3 = her age in three years time
C-3 = her age three years ago
