Hey guys- I know, this may be stupid of me to ask, BUT i do not have a knack for math. However, if you want to ask me about spanish, I will be able to help you haha.. anyway, this is the problem and I CANNOT figure this thing out...
2/x-5 + 1/2x = 5/3x^2-15x
solve for x by finding the LCD... thank you in advance =)
also- if i may ask, could you explain it step by stepedit on 11-4-2012 by Ketzer22 because: edited cuz the way it looked posted was different than when it was written

And to the person who said i was cheating- no, i'm not.. this problem has given me a particularly hard time.. I can do others that are like it.. I have even had my mom and girlfriend look at it and it has them stumped... hehe

This is definitely not some short problem. But I would make all the bottom the same equation. Anything at the = sign needs to equal to 0, so everything on the right has to go to the left. Then you have figure out your denominator, once you figure that out the numerator will be easy.
Ok the parenthesis makes it a bit more easier. BRB.edit on 11-4-2012 by Manhater because: (no reason given)

You have to breakdown the (3x^2-15) into 3x(x-5)
(x-5) will cancel the denominator for the numerator 2 which leaves 3x *2x and that would be 2 / 6x^2
Isn't that what your suppose to do in order find x?
1 * 3x^2-15
=
5(2x)
12x+3x^2-15=10x
3x^2+2x-15=0
(3x+3)(x-3)
I'm messing up somewhere
