Question about balanced wye - delta connection

[mingming]

i am confused on how to find the line currents when there is a line impedance in between the wye source and delta load... is it wrong to directly add the line impedance and the delta load without converting first the delta load to wye...? is there a way that i can find the line currents and phase currents...i know i cannot directly find the phase current on the delta load since there is a line impedance...plese help i am really having trouble on how to solve this kind of problem. Thank you in advance...

Hi
Simplest way to solve it ? convert delta (D) load to wye (Y) and then calculate line currents. Then go back to delta.
