One number is 3 less than a number. if 4 times the smaller number minus 3 times the larger number is 4, find the two numbers

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.

X=3 and y=4 is the answer
