Engineering Marvels of Electricity Boards

Challenge to all who know how to solve the problems mathematically? Please solve it.
1. Kirchoff's Current Law (KCL):
At every node, the sum of all currents entering a node must equal zero.
2. Kirchoff's Voltage Law (KVL):
The voltage law says that the sum of voltages around every closed loop in the circuit must equal zero.
Exercise:
Please apply Kirchoff's Current and Voltage laws to the following electricity nodes.
