Lose 12y yards.

Lose 5.2x yards.

What is the net yardage for these four plays?

Enter your answer as an expression, like this: 42x+53y

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.
