Dear Algebra,
The reason you cannot figure out
'Y' you and your 'X' are no longer together is because you pay too
much attention to who 'A' and 'B' are. Maybe just forget your 'X', don't worry about 'Y', and who cares about 'A' and 'B'? They're just another problem you
have to worry about. Just worry about
yourself.
Sincerely,
Not too happy math students
