Need help solving power network

Need help solving power network (power flow analysis)

I need help on solving this problem. I spent hours, but can't find it. Thanks in advance



The source voltages and impedances in the network below are in per-unit.
(a) Sketch the admittance diagram of the system and indicate all appropriate values on the diagram.
(b) Determine the bus admittance matrix
(c) Determine the voltages at each bus.

(a) All you have to do here is to convert the impedances to admittance and redraw the diagram, Y(admittance) = 1/Z(impedance). Ex. j0.5 = -j2
In order to solve the remainder of the problem you need to state which method of solving the network is required, (gauss seidel, newton raphson.....)

Thanks and yes, I figured out the first one. but the voltage part on left and right side, what should I do on the diagram?

I was solving it with Y11=y10+y12_y13....
to find out bus admittance matrix.
