THATS THW WHOLE QUESTION. IM THINKING THE ANSWER IS 18 YEARS OLD.
12+6
Would "12 years plus half of 18" equal to 18?
How about working out:
"12 years plus x/2 equals x"

SALLYS AGE IS 12 YEARS PLUS HALF HER AGE. HOW OLD IS SHE?
The problem is that we don't know Sally's age. All we know is that she is x years old and x equals 12 + x/2.
x = 12 + (1/2)x
(1/2)x = 12
x = 24
