Complete the ordered pair so it a solution of 2x-5y=13

2 x - 5y = 13

2 × -1 - 5 × -3 = 13

(-1, -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.

Idrk but i think u should figure out the n dia n then the units it will make it way more easier
