If the number p is 20 more than the number q using algebra write the relationship between p and q

All you have to do is write the equation out showing what q equals.
q=p-20

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.

Iam pretty sure its a sorry if im wrong
