Looking to automatically delete rows with certain values in 2 columns and sum=0 in another

[LordCrimsonKing]

Hello,

I am new and this is my first post, so please forgive me if I am posting this in the wrong spot.

I am looking for a way to automatically go through several thousand rows of data in a spreadsheet, comparing data in columns, and deleting affected rows. In example, if a row and another row contain the same value of data in columns A and B, and their sum equals zero in column C, those rows will be deleted.
