Which of the following is(are) the solution(s) to 111x +3-6?
o a. x-3
o b. x-
o c. xii
o d. x-

The correct answer is X-3

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.
