Are you familiar with combining resistors that are in parallel or series? That seems the most straightforward approach.

Is your current arrow for Iy, drawn as given in your problem? In your diagram it appears to be right over a node. (Are you familiar with the behavior of current with respect to Kirchoff's current law?)
