i dont get this question, if A, B, and C are known, then assuming the equation is A*y + B = C, then there can only be one value to Y doesn't matter what statements we are given...

Shouldn't the question be more explicit...by wording something like this -
How many different values for y are there such that A.y+B=C(A, B,and C are known) ?
How many different numbers are there such that A.y+B=C (A, B,and C are known) ? What numbers!!!!!

I did not understand the question when I read it.....after reading the explanation thats when I guessed that they are asking for number of possible values for y..

Do you agree....? What is the source, noboru?
