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

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#

#=-21n+3#

#-4+7(1-3n)#

Distribute

#-4+(7)(1)+(7)(-3n)#

#= -4 + 7 - 21n#

#= -21n+3#
