    Transposing a Formula
    Hello,
    After many pages of working, I've managed to work my way to an equation that looks like this:

    x=10ln(y/(5-15y))-26

    I now need to rearrange this equation to y=...
    No matter how many times I try I just can't seem to get it.
    I'm farily sure that the above equation is correct but the fact that I can't seem to rearrange it means I may have to go back to the beginning.
    I thought I might plead for some help from someone smarter than myself before I damage some poor wall with my head...

    You sir, are my new hero

    I can't believe I didn't think to flip the equation to cancel a y, I've done it so many times before.

    Thank you so much
