Both the question, and the bot's answer, make no sense to me

A y = 3xy = 3x
B y = 12xy = 12x
C y = 4xy = 4x
D y = 2x , are all silly statements

e.g.
y = 3xy = 2x , what is that supposed to mean?
that would be
y = 3xy and y = 2x, so using substitution we get ...
3xy = 2x
3xy - 2y = 0
y(3x - 2) = 0
y = 0 , x = 2/3, now what? where does the n come in ?

n = 2x
