A comma typically goes before parentheses if the sentence structure requires it. For example, in the sentence "She decided to go to the park (which was quite crowded), despite the weather," the comma is placed before the parentheses. However, if the parentheses are at the end of a sentence and the sentence does not require a comma, then no comma is needed.
That's called an "operator", for example, the plus sign in 3 + 4. The numbers are the "operands" - that is, the numbers (or expressions) operated upon. More precisely, a binary operator, since it works with two operands.

While it is true that citations are commonly placed within parentheses, they can also be presented in other formats such as footnotes or endnotes. The purpose of using parentheses for citations is to acknowledge the source of information without disrupting the flow of the main text.
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. If the parentheses were placed 7x - (4x - 9) = 7x - 4x + 9 = 3x + 9.
Parentheses are usually placed inside brackets.
