if,
ax+by= c,
ax+by=c,
can a or b ever be 0 ?
in other words, can you ever have a 0 number of variables?

Of course you can... if a = 0, you have an equation that would simplify to:
by = c
y = c/b (and since c and b are constants)
y = d
which would represent a horizontal line crossing the y axis at d
Same with b, only if b = 0 you would have a horizontal line

Yes you can, i think that the last person got the + mixed up with a multiplication because if a and b are 0 than the answers for b times y equals c, i also agree with the first answer

Yes. Either can be zero. But if a and b are zero, then c has to be too.

a OR b can be zero, not both.
