Simplifying w/ exponents

  1. Mar 7, 2013 #1
    1. The problem statement, all variables and given/known data
    (2x+3x)/6x = 2-x+3-x

    I've tried moving the 6 above, splitting it up and so... but i can't figure how to do it. It must be pretty simple, but im just not seeing it. all helps appreciated!

    Start by "splitting" the left side into two fractions, like this:
    [tex]\frac{a+b}{c} = \frac{a}{c} + \frac{b}{c}[/tex]

    i certainly did that

    (1/2)^x+(1/3)^x... which is the same as flipping them over and making the exponential -x. cool
