Symple Equation Manipulation

  1. Sep 20, 2010 #1
    Manipulate "d = 1/2 (Vf + Vi) t" to find Vi

    Heres my attempt:

    d = 1/2 (Vf + Vi) t
    d/2 = (Vf + Vi) t
    (d/2) / t = Vf + Vi
    ((d/2) / t) - Vf = Vf + Vi

    I am pretty confident that i did this right but the equation seems to be a little funny looking and I just want to confirm with some pros here, thanks for reading and replying!

    not quite- 2d/t-vf=vi be careful with your fractions!
