    Hi. Actually, this is embarrassing, but my question is simply an algebra question. I know the equation and I know the answer, but I can't remember how to GET the answer. Can someone please walk me through this very simple algebra issue?

    Equivalent resistance in a circuit = 26 ohms
    R1 and R2 are parallel resistors; R1 = 55 ohms
    R1 and R2 are in series with R3, which = 12 ohms.
    Find R2.

    The equation, as given by my professor, is:

    26 = 12 + [1 / (1/55) + (1/R2)]

    (Answer = 19 ohms)

    I just can remember how to solve for that R.

    Thank you!
