X= can be anything, there is nothing to stop me from saying X=1 which would make your answer (-2)(2) which would be -4. If I use a X=2 theory then your answer would be (1)(-1) = -1 so on and so forth.

The correct answer was right here, the very first post after the question. You can't solve for variables where the variable isn't given by pretending that the variable is a particular number. Welcome to basic algebra.

edit: Also, chuckles at the solution fail for the question in the OP.

[QUOTE=Rosie;106058]If you solved it as 48/X(9+3) = 48/12X if x=2 then it is 48/ (2)12 which equals 2. The question as it is written is confussing. If you had 48/2*(9+3) it would be 288. But if the denominator is 2(9+3) it is 2, because you would solve the denominator before you divide. So is it 48/2 * (9+3) or 48/(2(9+3))?[/QUOTE

What I meant was if the problem is
48
___
2(9+3) you cannot divide 48 by 2 withouth first solving for the denominator. Using a / as a division symbol screws up the look of the problem.

Wolfram Alpha awaaaayyy

If your referring to the search engine, no. Not everyone is stupid.

Fucking shit o.O your right, division symbol / <- works as a parenthisis

/ = fraction or ratio, generally follows all rules of division so we use it as that
- with the two dots = division we know from PEMDAS >.<

this equation should very well be clarified, we dont know if its

48
------
2(9+3)

or

48
--- (9+3)
2

These are two completely different equations, but both could be applied to OP question

no. it's directly left-to-right. there is no clarification needed. any ambiguity as to the original intention of the problem does not effect the answer. the answer as it is written is 288.
