Given the expression:


-(-3u+x)+2(-x-2u)

You can simplify it as follows:

1. Apply the Distributive Property. It is important to remember the Sign Rules for Multiplication:


\begin{gathered} +\cdot+=+ \\ -\cdot-=+ \\ -\cdot+=- \\ +\cdot-=- \end{gathered}

Then:


=3u-x-(2)(x)-(2)(2u)
=3u-x-2x-4u

2. Add the like terms (these are the terms that have the same variables with the same exponents):


=-3x-u

Hence, the answer is:


=-3x-u
