Which shows this equation in standard form? 6 – 2(x – y) = 3x + 5 a) 5x – 2y = 1 b) 5x – 2y = –1 c) 5x + 2y = 1 d) 2x – 5y = 1

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.
