Also, you word problem doesn't match your results.
"Question - What number do you end up with when you divide 48 by twice the sum of 9+3? Express this question in the form of an algebraic equation and show each step of your work."
That would be written out as follows:
48 / (2 x (9 + 3)) = n

48÷24 = n then at this step you err.
48÷2(12) = n is the same as
48÷2*12 = n
BY CONVENTION, you then proceed from left to right, the first operation is division:
24*12= n
and THEN multiplication:
n= 288,
not
n = 2

Did you read the part of my post that says "There is a convention that says you do implicit multiplication before division. Based on that convention, you get:"???
