PLEASE HELP ME!!! Find the missing values of x and Y from the following equal ordered pairs.
a) (2x + y, 2) = (1, x - y)
b) (x+2y,3)=(-1,2x-y)​

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.
