Question

Can you simplify this for me -(-3u+x) + 2 (-x-2u)

Answer 1

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`
