In the three phase system of Fig. 8.4, calculate the magnitude of the line
voltage V and the input power factor.
Data
V 1 = 400 V, Z ̇ L = 0.1 + j0.2 Ω, P 2 = 10 kW cos φ 2 = 0.6, Z ̇ 1 = 5∠60 ◦ Ω
delta connected, f = 50 Hz.

The results are:
V=462.76
Cosphi=0.506

In the image attached there is my solution. Could you please tell me where is wrong?

If you could upload a more clear picture I'd be happy to try help you. Just finding it difficult to see the circuit etc.
