1. solve for x. show the equation you used and your work. for the 1st

2. solve for x. show the equation you used and your work. for the 2nd

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.
