Removing Mirrored Duplicates

[sgibson34]

My data has quite a few instances where the rows are duplicate, but the values are just mirrored in different columns. I want to remove the duplicate instance and keep the original. For example, if row1 = x   y    and row2 =   y    x     I want to get rid of the second row but keep the first.

I could use this if i could concatenate the data from the two columns together, how would i do that?
