Homework Help: Something simple I forgot how to do!

  1. Nov 14, 2011 #1
    Something simple I forgot how to do! :(


    For the life of me, I can't remember how to do this!! I tried figuring it out from an example, but with no joy.

    I need to solve for Vi.

    (Vi - 0.58) = (4.42 - Vi).

    I'm sure if I just played around with number I could find them, but I want to know the correct way to do it ...so, if anyone could point me in the right direction, I would be forever in your debt!

    Thanks in advance.

    Your equation can be written more simply, without the parentheses and without the subscripts, as
    V - 0.58 = 4.42 - V.

    Add V to both sides, and then it should be obvious what to do next.

    Ahh of course!

    I don't know why I didn't see that!!

    Again, many thanks.
