ok i know that [tex]R_{1}[/tex] and 35[tex]\Omega[/tex] are in series and [tex]R_{2}[/tex] is in parallel to the top 2 resistors but I am obviously making errors either in how i set up the problem or in my calculations. I have tried (1/[tex]R_{2}[/tex]) + (1/2R) = 3/2R (as shown in my book) and then invert to show 2/3(R) and the answer i'm getting is wrong.. please help
