5\sqrt{3}x+\sqrt{3}+42=12\sqrt{3}x+3\sqrt{3}
Multiply both sides of the equation by 3.
5\sqrt{3}x+\sqrt{3}+42-12\sqrt{3}x=3\sqrt{3}
Subtract 12\sqrt{3}x from both sides.
-7\sqrt{3}x+\sqrt{3}+42=3\sqrt{3}
Combine 5\sqrt{3}x and -12\sqrt{3}x to get -7\sqrt{3}x.
-7\sqrt{3}x+42=3\sqrt{3}-\sqrt{3}
Subtract \sqrt{3} from both sides.
-7\sqrt{3}x+42=2\sqrt{3}
Combine 3\sqrt{3} and -\sqrt{3} to get 2\sqrt{3}.
-7\sqrt{3}x=2\sqrt{3}-42
Subtract 42 from both sides.
\left(-7\sqrt{3}\right)x=2\sqrt{3}-42
The equation is in standard form.
\frac{\left(-7\sqrt{3}\right)x}{-7\sqrt{3}}=\frac{2\sqrt{3}-42}{-7\sqrt{3}}
Divide both sides by -7\sqrt{3}.
x=\frac{2\sqrt{3}-42}{-7\sqrt{3}}
Dividing by -7\sqrt{3} undoes the multiplication by -7\sqrt{3}.
x=2\sqrt{3}-\frac{2}{7}
Divide 2\sqrt{3}-42 by -7\sqrt{3}.
