As there are no parentheses then the expression stated can be simplified as follows :-
7x - 4x - 9 = 3x - 9
If the parentheses were placed (7x - 4x) - 9 then the result would be the same.

Do you simplify while using the distributive property to write an expression?
When using the distributive property to write an expression, you do not simplify within the parentheses before applying the property.
