Finding various currents around the circuit

[captjackAV]

Homework Statement

I have attached the circuit diagram to this thread.
V=12V, R1=2kΩ, R2=2.7kΩ, R3=1kΩ, R4=5.1kΩ.

Find I1, I2, I3, I4, I5, I6. Find VA, VB, VC, VD.
I just don't know how to apply kirchhoffs law to find the current and the voltage. I don't expect to have all answered. If someone can explain how to find at least 1 current and 1 voltage across a resistor, i can try to find the rest. Thank you in advance.

Homework Equations

I6=I1+I2
I1=I5+I3
I4=I2+I5
V=I/R

The Attempt at a Solution

I1= v/R1=12/2Ω=0.006A
I2= v/R2=12/2.7Ω=0.0044A
I6=I1+I2 = 0.0104A
VA=12V

Can you replace 2 of the parallel resistors with a single resistor? Simplify the circuit this way so you end up with something to which you can readily apply Ohm's Law.
