posted by on .

loga(x-5)-loga(x+9)=loga(x-7)-loga(x+9)

all the a's are lower

please show work

  • math-please help,need quickly - ,

    log [(x-5)/(x+9)]= log[(x-7)/(x+9) ]

    (x-5)(x+9) = (x-7)(x+9)

    x-5 = x- 7
    no solution

  • math-please help,need quickly - ,

    x-5/x+9 is equal to x-7/x+9

    (x+9 )(x-5) is equal to (x-7)(x+9)
    x2-5x+9x -40 equals x2-9x-7x-63
    nw solve from there:)
