3n+6=9\left(6-n\right)
Use the distributive property to multiply 3 by n+2.
3n+6=54-9n
Use the distributive property to multiply 9 by 6-n.
3n+6+9n=54
Add 9n to both sides.
12n+6=54
Combine 3n and 9n to get 12n.
12n=54-6
Subtract 6 from both sides.
12n=48
Subtract 6 from 54 to get 48.
n=\frac{48}{12}
Divide both sides by 12.
n=4
Divide 48 by 12 to get 4.
