Answer: x=9

Explanation:

  1. Multiply across so you get x-21+2x=6.
  2. Then add "x" and "2x" together to get 3x.
  3. Then u add the -21 to 6 and then get 27.
  4. Lastly, you divide 27/3x and get x=9.

Answer:


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
