Answer 2

`x=9`

Explanation:

We begin with the equation:
`x-(21-2x)=6`

The first thing that we need to do is distribute the negative into the parenthesis

`x-(21-2x)=6\\\\x-21+2x=6`

Now we can combine the like terms on the left side

`x-21+2x=6\\\\3x-21=6`

Next add 21 to each side

`3x-21=6\\\\3x=27`

Lastly, we can divide each side by 3

`3x=27\\\\x=9`
