    Please check your typing, and use brackets to avoid ambiguity.

  • college algebra - ,

    in the problem there are no brackets
    x over x minus x/over x-4 equal -4 over x-4 solve each rational equation if it has no equation state so. simply with necessary

    Please help me

  • college algebra - ,

    So it is

    [x/(2-x)]/(x-4) = -4/(x-4) ?

    Where does the third equality come from ?

    Can you see why brackets are absolutely necessary here?

    ok, first multiply both sides by x-4 to get
    x/(2-x) = -4
    now multiply both sides by 2-x
    x = -4(2-x)
    x = -8 + 4x
    -3x = -8
    x = 8/3

    Lastly, what does "...if it has no equation state so. simply with necessary " mean ?
