Breakdown, and find the total resistance for this circuit.

2. Relevant equations

V=IR

Parallel Circuits - 1/R_{tot}= 1/R_{1}+ 1/R_{2}...

Series Circuits - R_{tot}= R_{1}+ R_{2}

3. The attempt at a solution

Please dont mind the resistor units, they're all in kΩ.

Basically, I try to breakdown the circuit into its most simple form. I feel however that in my 3rd recreation I'm doing something wrong.

In the first circuit diagram, I took the two resistors on the right and made them one (as they're in series). I then considered the two resistors on the far right in parallel, finding the new resistance. However --- is this correct, as there is the 6 ohm resistor just before it. Must I include this in the R_{parallel}equation? I have tried this but still I get an incorrect answer, of 2.67kΩ.

My answer as done in the picture is 2.5kΩ. However the supposed answer is 3kΩ.

And no there isn't supposed to be a rounding of the answer.

Please help!
