But thats not the way the original question is written.
That is the same as (48/2)(9+3)
You do left to right on the original question just you have to do left to right on the top of the equation and left to right on the bottom before you an do the division.

the issue is grammatical:
if it were written:
48 ÷ 2 * (9+3)
then, it would be 288.
but as written it essential evaluates this way:
x = (9+3)
48 ÷ 2x
which is 2.
just because 2(x) and 2 * (x) use the same math operation internally, doesn't mean they are treated the same way in an equation.
