Gino packs his blue and green pencils into boxes. he puts 8 pencils in each box. how many boxes does gino have?

There's no way to know this without knowing the number of pencils he started with

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.
