Question

can you please solve x-(21-2x)=6

Answer 1

Answer:

$x=9$

Step-by-step 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

$3x=27\\\\x=9$

Answer 2

Answer: x=9

Step-by-step 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.
