9x-18=3\left(x-4\right)+3x
Use the distributive property to multiply 3 by 3x-6.
9x-18=3x-12+3x
Use the distributive property to multiply 3 by x-4.
9x-18=6x-12
Combine 3x and 3x to get 6x.
9x-18-6x=-12
Subtract 6x from both sides.
3x-18=-12
Combine 9x and -6x to get 3x.
3x=-12+18
Add 18 to both sides.
3x=6
Add -12 and 18 to get 6.
x=\frac{6}{3}
Divide both sides by 3.
x=2
Divide 6 by 3 to get 2.
