How old am I?
My age today is three times what it will be three years from now minus three times what my age was three years ago. How old am I?
I am 18. If I was 18 then three times my age three years from now would be 21*3 (63). Three times my age three years ago would be 15*3 (45). Subtract 45 from 63 and I am 18.
