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