3\sqrt{3}x-\sqrt{3}x-18=0
Multiply both sides of the equation by 3.
3\sqrt{3}x-\sqrt{3}x=18
Add 18 to both sides. Anything plus zero gives itself.
2\sqrt{3}x=18
Combine 3\sqrt{3}x and -\sqrt{3}x to get 2\sqrt{3}x.
\frac{2\sqrt{3}x}{2\sqrt{3}}=\frac{18}{2\sqrt{3}}
Divide both sides by 2\sqrt{3}.
x=\frac{18}{2\sqrt{3}}
Dividing by 2\sqrt{3} undoes the multiplication by 2\sqrt{3}.
x=3\sqrt{3}
Divide 18 by 2\sqrt{3}.
