    Solve the log function using graphing calculator

    123x-1= 5982x-3

    I need to simplify the equation first and then plug it into a calculator to solve for x. The problem is, I don't know how to simplify this type of equation with two exponents..help

    Re: Solve the log function using graphing calculator

    \log(12^{3x-1}) = \log(598^{2x-3})

    (3x-1)\log{12} = (2x-3)\log{598}

    now graph ...

    y = (3x-1)\log{12} - (2x-3)\log{598}

    ... and look for the zero.

    Re: Solve the log function using graphing calculator

    But the equation y=(3x-1)log12-(2x-3)log598 is not simplified ! It has to be simplified until it is in terms of x. how do i do that?

    the equation is in terms of x ... do you mean solve for x ?

    Re: Solve the log function using graphing calculator

    yes, that's what i mean. I mean I have to make the simplified equation look like x=something so that I can easily put it into the calculator. in our class we were told not to graph them on the graphing calc

    Re: Solve the log function using graphing calculator

    I'm not sure, but I think your equation was in terms of y instead.

    Re: Solve the log function using graphing calculator

    (3x-1)\log{12} = (2x-3)\log{598}

    this is a linear equation ... you try solving for x. remember that \log{12} and \log{598} are just constants.
