Simple Question

  1. Aug 14, 2012 #1
    Hello fellas.

    I have this formula that encodes data:

    OUTPUT = (Data * 7) + (Data * 2) + 8

    So in this case, if I have the OUTPUT, what is the data. What formula can I use if I have OUTPUT to get Data? Thanks much!!!

    Hey vladtess and welcome to the forums.

    Hint: Try re-arranging to get Data = something else. I will provide one hint:

    OUTPUT = Data*7 + Data*2 + 8 = 9*Data + 8. Do you remember how to balance equations to get one in terms of the other (using arithmetic)?

    Hey Chiro, thanks, i happened to remember the outcomes.

    It comes out to (OUTPUT-8)/9 = data

    Is that correct?

    Thanks much for making me think a little!! ))
