x-y=4
x=y+4

how does this tell us that x and y are multiples of 4?

I understand that x is 4 more than y but not the above.

Thx.

i'll move the post to DS section then.

Could you please post the whole context, it's difficult to say anything with the current information. I mean, the entire question, and the OE/statement which is giving rise to such doubt.

sorry i actually misread the question.

if your interested, the question was:

what is the GCF of x and y?
(1) x and y are both divisible by 4
(2) x-y=4

Show Spoiler
OA: (C)

i thought x=y+4 means that x and y are multiples of 4 (misread).
