Answer:
[tex]\boxed{\bold{-4nx-ny+2x-6y}}[/tex]
Explanation:
Rewrite:
= [tex]\bold{-n\left(4x+y\right)+2\left(x-3y\right)}[/tex]
Expand [tex]\bold{-n\left(4x+y\right): \ -4nx-ny}[/tex]
= [tex]\bold{-4nx-ny+2\left(x-3y\right)}[/tex]
Expand [tex]\bold{2\left(x-3y\right): \ 2x-6y}[/tex]
= [tex]\bold{-4nx-ny+2x-6y}[/tex]
Mordancy.
