Hi,

I need to simplify this circuit of resistors.

Image of problem:

The Resistor equivalent is 9 ohms, and the solution for R is actually 15 ohms. However, I'm not sure how to get this answer. I think I am getting stuck at the point in my solution on step 4/5 where I seem to have 3 resistors connected to 1 node, but the circuit looks confusing.

I attempted to simplify the resistors in step 5 as resistors in parallel, but I don't think I am getting the right answer.

parallel = 1/Rtotal = 1/R1 + 1/R2 + 1/R3

Series = Rtotal = R1 + R2 + R3

Any help would be appreciated.
