• Make sure complex mode is active;
• Press 2 x<>y 1 ENTER 4 x<>y CLx 3 x.
  

This leaves -5 in X and 10 in Y, as it should. The CLx disables stack lift and allows the 3 to be entered without changing Z and T.

That’s an improvement compared to my method. It looks like I’ll be using your method instead. Thanks!
