Lets make it 48/2(x), where x=9+3. Same equation.
= 48 / 2 (x)
= 48 ÷ 2 * x
= 24 * x
= 24 * (9+3)
= 288.
Unless you can provide some proof that a / sign means that absolutely everything in the entire equation following that sign is now a denominator, or that 2x != 2*x, or at least 2*x is not 'as important' as 2x, then I don't know what to say.

Like I said, it sounds retarded isolated but it changes how the equations react.
I know that 2 is 'latched' to (9+3) because it's written as 2(9+3) and not 2*(9+3).
In your example, you need to solve for X first, because it's 2 quantities of x, not just 2 times x. The isolated product is the same, but you need to do it first to simplify the equation.
Deryk, I know FOIL is for two separate binomials... don't really give a fuck in this case, it's the same logic.
mortum, we can't assume the problem is written as anything really, because it wasn't written  it was typed. That's why we're running into issues. If this person wrote it out in standard notation, it'd be obvious as to which term was a denominator and which was supposed to be dealt with after the division. In this case, since it's written as 2(9+3), as per my explanations above, we have to assume that it's (48)/(2(9+3)).
In the math classes you'd have taken, the professor (hopefully) wouldn't be dumb enough to be as ambiguous as the author of this equation.
