    10-5(2x+3)=8(3x-2)-12x
    10-10x+15=24x-16-12x
    25-10x=12x-16
    41=22x
    x=41/22

    the more complicated question is
    x^x=2

    @mniip 
    The answer is aproximately:
    1.559610469461<x<1.559610469465

    @Mushroom (View Post)
    can you give a formula showing the root?
  • Mushroom     9th Jan 2012 Member 0 Permalink

    Basically:

    x=x??(2)


    EDIT: Website can't read characters, and I don't know how to reformulate it.

    x equals the xth root of 2

    i mean something like:
    X=something_without_x'es

    I think it is not really possible.
    To find, I'd have to make tons of operations and I don't want to. So...
