2016÷[25-(3x+2) ]

To simplify the expression 2016 ÷ [25 - (3x + 2)], we first need to simplify the expression inside the brackets.

25 - (3x + 2) = 25 - 3x - 2
= 23 - 3x

Now, the expression becomes:

2016 ÷ (23 - 3x)

To simplify further, we can factor out a common factor of 3 from the denominator:

2016 ÷ 3(23/3 - x)
= 2016 ÷ 3(7 - x)
= 672 ÷ (7 - x)

Therefore, the simplified expression is 672 ÷ (7 - x).
