Give an example of a logarithmic equation that cannot be solved and explain why it cannot be solved.

  • math -

    work backwards
    You know that we cannot take the log of a negative number, so
    let x = -5
    2x = x-5

    take log of both sides

    log 2x = log ( x-5)

    now try to solve it
