**URGENT: Delta-Wye transformations**

Hello there. In my electrical fundamentals class (a 201 level class), we just barely started Delta-Wye transformations. However, the homework that is due online tonight uses full transformations...confused, I have just tried to work through this using the book. I have become stuck...

My homework is due tonight at midnight, so please help asap?

## Homework Statement

All attached

## Homework Equations

Ohm's law, and...I don't know the other ones

## The Attempt at a Solution

I have worked through most of the solution in the jpg. However, I am stuck. I know I need to find I, because if I can find I, it would be very simple to use Ohm's law in the original circuit.

I have tried to add the series and do parallel to leave

16.87 + 9.62 || 55.5 = Rd

then Rd || 36

Then you are left with a simple circuit to determine I, which I calculated to be 4.4A.

Can someone please help? haha
