I've been doing my math homework for about an hour now, and have hit a stumper. Hoping someone might be able to help.
Working on solving Proportions.
X````2X+5
-- = --------
3``````6
Pay no mind to the hashes, they are just there for spacing.
I'm attempting to solve through distributive property.
6(x) = 3(2x+5) =
6x = 6x+15 =
6x-6x = 15 Now here is where I hit the snag, because when I simplify this, I get
0 = 15
And we all know that's not possible. Is the answer null? It doesn't talk about in this section what to do if they don't equal out. Am I doing something wrong?

x=3, 2x+5=6? because that is obviously impossible assuming the x values are the same.
It's a fraction, could also be read as X/3 = (2X+5)/6
@AC: I'm 28, this is College math, I'm hardly a kid. I'm sorry you are so intelligent that you have to suffer us menial people who cannot solve every problem by themselves. I guess you don't ever ask for help?
I blame it being 2am and the internet being a poor medium for maths. On topic it does look like you're correct, x/3=(2x+5)/6 6x=3(2x+5) 6x=6x+15 0=15. Are you sure the first part is correct?
Oh the times I wish that the standard of teaching I got wasn't gak...
If anyone gets it can they please explain it to me? I'd like to know this stuff so I can look like I recieved an education

the fraction itself is straight from the book. But when I first cross multiply it immediately becomes 6x = 6x +15 which is already false. I just don't know.
@Avatar: normally to solve for a variable (a letter) in a proportion (two factions that are suppose to equal one another), you multiply opposing tops and bottoms, and solve through algebraic equation. But normally there isn't a variable on both sides of the equal sign.

Also now i cant stop thinking about it! Curse you!
I can't stop either, and i'm still learning how to do it xD

but either one is appropriate; this question is a real bastard; and I must solve it!

After consulting one of my friends who is awesome at maths, we've agreed that there is absolutely no solution, even with imaginary numbers (well, he told me that part, I just agreed because I trust his knowledge and capabilities, considering that he's attending Imperial College and that I know how good he is at maths).

Indeed, everything he's answered could well have been an exceedingly lucky guess. It's exceedingly improbable, but possible.

you have to get both sides to equal each other. So
2x= 2x+5
6 6
2x- (2x +5)
6
0+5/6=0
No solution.
From whom are unforgiven we bring the mercy of war.
Every so often in highschool we'd come across a problem in our homework that had a typo, so that there was no solution or a really ridiculous answer. It generally just showed us the teacher wasn't bothering to do the problems before assigning them to us, he was just picking stuff out of the book and assuming it was okay.
This looks like one of those instances.
“We may observe that the government in a civilized country is much more expensive than in a barbarous one; and when we say that one government is more expensive than another, it is the same as if we said that that one country is farther advanced in improvement than another. To say that the government is expensive and the people not oppressed is to say that the people are rich.”

Imaginary numbers aren't that confusing really, i is just the square root of minus one and 2i is the square root of minus 4 etc. This is really basic algaebra so there is no need for imaginary numbers, they only really come into play with simple algebra when you get equations with x^2 (x squared) or higher powers of x.
