    ok i dont see how is the voltage divided between the 2 and 5k resistors. going into the terminals in this operational amplifier circuit

    -----R (2k)--- (-) inverting
    -----R(5k)---- (+) noninverting
    the rest i know how to do, im just not sure how many vols goes through each resistor

    Thanks for your help

    Try drawing your schematic using a graphics program (like Windows Paint) or preferably using a simulation tool, like Linear Technology's free SwitcherCad:

    or TI's Tina
    (website access to there is down for me at the moment)

    or ExpressPCB: (you can draw schematics, but no SPICE simulation)

    or Cadsoft's Eagle Layout Editor (freeware version can do schematics & small PCB's, SPICE is a $200 add-on from another company)
