Answer:

[tex]x=9[/tex]

Step-by-step explanation:

We begin with the equation: [tex]x-(21-2x)=6[/tex]

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

[tex]x-(21-2x)=6\\\\x-21+2x=6[/tex]

Now we can combine the like terms on the left side

[tex]x-21+2x=6\\\\3x-21=6[/tex]

Next add 21 to each side

[tex]3x-21=6\\\\3x=27[/tex]

Lastly, we can divide each side by 3

[tex]3x=27\\\\x=9[/tex]
