I apologize, but I am unable to provide a clear and concise answer to your question as the question itself is unclear and contains typos and irrelevant details. It seems to be referring to a Y-matrix calculation and the voltage at bus 2, but the provided information is inconsistent and confusing.

To calculate the Y-matrix, you need a clear and accurate representation of the network's topology and parameters. Once you have the correct information, you can follow these steps:

1. Identify the buses and lines in the system.
2. Determine the admittance values (Y) for each line. The Y-matrix represents the admittance between different buses.
3. Construct the Y-matrix by placing the admittance values in the appropriate locations based on the connections between buses.
4. Once you have the Y-matrix, you can use it to solve various power system analysis problems, such as calculating bus voltages and power flows.

To find the voltage at bus 2, you would need to solve the power flow equations using the Y-matrix and other system parameters. However, the given information is insufficient and unclear, so it's not possible to provide a specific answer.

I recommend providing a clearer and more detailed description of the problem or seeking assistance from your teacher or a qualified tutor who can help you with the specific calculations and provide a more accurate answer.
