    Solving equation for x.

    My chemistry text gave me this equation and the algebra I'm using doesn't give me the right answer. Can someone show me the steps to get to the right answer?

    [(.449)(400)(32.8-20)] + [(4.184)(1000)(32.8 - x)] = 0

    solve for x

    Thanks

    [(.449)(400)(32.8-20)] + [(4.184)(1000)(32.8 - x)] = 0

    (4.184)(1000)(32.8 - x) = -(.449)(400)(32.8-20)

    (32.8 - x) = -[(.449)(400)(32.8-20)]/[(4.184)(1000)]

    - x = -[(.449)(400)(32.8-20)]/[(4.184)(1000)]-32.8

    x = [(.449)(400)(32.8-20)]/[(4.184)(1000)]+32.8
