Please help me out! the question is Lin subtracted 3 x 2 then 3 x 1 and lastly 3 x 9 earlier Andre subtracted 3 x 200 and then 3 times 10 and lastly 3 x 9 why did they have the same quotient?

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.
