Can you show why the answer to this question R = 199 ohm?

 

In the circuit shown in the figure, if the source voltage is V = 28.2 Volts and the
current flowing (top to bottom) through the 4000 resistor is I。 = 5.9 mA, find
the value of the resistor R in units of (Ohms).
Hint: Using the voltage and current given, use KVLs, KCLs, and Ohm's Law to
find voltages across and currents through all the resistors in the circuit. Once
you know the voltage across and the current through the resistor R, then you
can find the value of R from Ohm's Law.
