3\left(-\frac{\sqrt{3}}{3}\right)x-3\sqrt{5}=0
Multiply both sides of the equation by 3.
\frac{-3\sqrt{3}}{3}x-3\sqrt{5}=0
Express 3\left(-\frac{\sqrt{3}}{3}\right) as a single fraction.
-\sqrt{3}x-3\sqrt{5}=0
Cancel out 3 and 3.
-\sqrt{3}x=3\sqrt{5}
Add 3\sqrt{5} to both sides. Anything plus zero gives itself.
\left(-\sqrt{3}\right)x=3\sqrt{5}
The equation is in standard form.
\frac{\left(-\sqrt{3}\right)x}{-\sqrt{3}}=\frac{3\sqrt{5}}{-\sqrt{3}}
Divide both sides by -\sqrt{3}.
x=\frac{3\sqrt{5}}{-\sqrt{3}}
Dividing by -\sqrt{3} undoes the multiplication by -\sqrt{3}.
x=-\sqrt{15}
Divide 3\sqrt{5} by -\sqrt{3}.
