If you are looking to have this expression simplified see a process below:

Explanation:

First, expand the terms in parenthesis by multiplying each term within the parenthesis by the term outside the parenthesis:

-4 + color(red)(7)(1 - 3n) =>

-4 + (color(red)(7) xx 1) - (color(red)(7) xx 3n) =>

-4 + 7 - 21n

We can now combine the like terms, these are the constants in this problem:

-color(blue)(4) + color(blue)(7) - 21n =>

3 - 21n
