    Find the x - Log

    Hello every body!

    How can i solve this problem:

    $\displaystyle
    1+\frac{log_3(12-X)}{log_3X}=\frac{3}{log_3X}
    $

    Thank you!

    Start by multiplying both sides through by $\displaystyle \log_3x$

    giving

    $\displaystyle \log_3x+\log_3(12-x)=3$

    now use the rules

    $\displaystyle \log_ac+\log_ac = \log_a(b\times c)$ and $\displaystyle \log_aa=1$
