help me solve
6/z+8 = 5/z-3?
do i first find the lcd?

  • ALGEBRA -

    I will assume that you mean
    6/(z+8) = 5/(z-3)
    Parentheses are very important when you write equations on a single line, as here.

    Cross multiply to get
    6z - 18 = 5z + 40
    Now combine terms
    z = 58

    You could look for an LCM, but that step is not necessary. The answer would be the same.

    Maybe I wrote the problem wrong...
    6 = 5
    z+8 4+x

    is that the same as what i put earlier?
