Idont know how to do this im gonna freaking blow my brains out

PQR ~ PSQ, PQS ~ QRS (edit: and PQR ~ QSR woops forgot that!). So A, B and D.

Sorry the photo's messy, just wanted to show my ugly process lol.

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.

The answer simplified would be. -6300x
