Please don't 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 Rparallel 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!
