    1. The problem statement, all variables and given/known data
    Can someone please give me insight on how to solve for the total resistance of this circuit? Thank you

    2. Relevant equations

    You can't.
    1. the picture does not show a circuit.
    2. the picture does not show the two points that the resistance is to be taken between.
    3. there appears to be a short-circuit between the left and right-most extreme nodes.

    Once the above issues are sorted out - you will find the total resistance by simplifying the circuit. It can help to redraw it.

    Thank you for the scrutiny. Is this satisfactory now? I am sorry I there are still errors to tend to in the diagram, I hope I was able to convey enough information this time

    Total resistance between nodes A and B

    I don't see any symmetry that would help you out here so it seems to me you'll just have to do a ton of delta-Y transforms and simplify the circuit bit by bit. Looks to conceptually trivial but VERY messy to actually carry out.

    I suggest a box of assorted precision-resistors and a good ohmmeter.

    I'm tempted to say "about 2 ohms".

    There is a 1 and a 2 "in series" between a and b with mostly higher values "in parallel".

    If you model it as a 1+2 in parallel with a 3+4+5 you get about 2.4 Ohms.
