Can y’all help me solve this two step equation?

1=x/3-5

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.

For the first question the answer is a, for the second c, for the third d, for the 4th b, for the 5th a
