3\left(x+3\right)+2\left(3x-6\right)-\left(9-x\right)=6
Multiply both sides of the equation by 6, the least common multiple of 2,3,6.
3x+9+2\left(3x-6\right)-\left(9-x\right)=6
Use the distributive property to multiply 3 by x+3.
3x+9+6x-12-\left(9-x\right)=6
Use the distributive property to multiply 2 by 3x-6.
9x+9-12-\left(9-x\right)=6
Combine 3x and 6x to get 9x.
9x-3-\left(9-x\right)=6
Subtract 12 from 9 to get -3.
9x-3-9-\left(-x\right)=6
To find the opposite of 9-x, find the opposite of each term.
9x-3-9+x=6
The opposite of -x is x.
9x-12+x=6
Subtract 9 from -3 to get -12.
10x-12=6
Combine 9x and x to get 10x.
10x=6+12
Add 12 to both sides.
10x=18
Add 6 and 12 to get 18.
x=\frac{18}{10}
Divide both sides by 10.
x=\frac{9}{5}
Reduce the fraction \frac{18}{10} to lowest terms by extracting and canceling out 2.
