Deleting Correlating Positive and Negative Numbers based on Criteria

Dear All,

I have a large spreadsheet that i am trying to cleanup. it contains thousands of rows where it shows a positive transaction with a matching negative transaction.

what i want is to delete that matching transaction based on following condition;

if matching postive and negative transaction alongwith amount is reconcile with ACCOUNT NO then both entries should be deleted.

this is previously solved with VBA but i am unable to modify according to my need.

i have attached the sheet for ease of reference.

thanx and cheers.
