Which expression is the simplest form of -(4x + y)n + 2(x - 3y)

Marina86 [1]

Answer:

$\boxed{\bold{-4nx-ny+2x-6y}}$

Explanation:

Rewrite:

= $\bold{-n\left(4x+y\right)+2\left(x-3y\right)}$

Expand $\bold{-n\left(4x+y\right): \ -4nx-ny}$

= $\bold{-4nx-ny+2\left(x-3y\right)}$

= $\bold{-4nx-ny+2x-6y}$
