question, 1. Is the load current IL [A] equal to the sum of current I1,I2 flowing to each transformer? If not for what reason?

A 4-bus three-phase power system consists of the following equipment: • Generator 1 connected to bus 1 with a rated power of 20MVA, rated voltage of 20 kV, and a series reactance of 0.4 p.u. • Generator 2 connected to bus 5, with a rated power of 12MVA, rated voltage of 10 kV, and a series reactance of 0.3 p.u. Transformer 1 connected between buses 1 and 2, is wye-wye connected with a rated power of 20 MVA, rated voltages 20/100 kV, and a series reactance of 0.1 p.u. • Transformer 2 connected between buses 4 and 5, is wye-wye connected with a rated power of 12 MVA, rated voltages 12/110 kV, and a series reactance of 0.15 p.u. • Transmission Line 2-3 connects buses 2 and 3 and had a series impedance of 50 + j75 ohms. • Transmission Line 3-4 connects buses 3 and 4 and had a series impedance of 40 + j80 ohms. • Load A connected to bus 3 and abosorbes20 MW and 10 MVAR. The voltage at bus 3 is 105 kV. 1) Draw the one-line diagram for the system. 2) Draw the per-unit, per phase…

This is a practice question from my Introduction to Circuits course. I'm not sure how to even start this. Thank you for your assistance.
