Kirchoff's Law

Please see attached. Numerical Answer is included in attachmnet I really need to see the step by step process to solve this problem. Draw the diagram of the loop used for each equation. Have fun... Thanks P.S. Scaned answers are acceptable, please write legibly.

Write equations for circuit

Can someone help with the circuit in the attachment? I need to write the equations for the circuit, using loop or another method. From the equations, transform into Laplace equations and solve for the current through the 5 ohm resistor. (See attached file for full problem description)

zener diode

Can You show me how to solve the following: If a 5k resitor is connected between the cathode of a 6.2V ZENER diode and a 12V power supply.The anode of the diode is connected to 6V.How much current will flow through the diode?

complex power
