3\left(x-10\right)=x\sqrt{3}
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 3x, the least common multiple of x,3.
3x-30=x\sqrt{3}
Use the distributive property to multiply 3 by x-10.
3x-30-x\sqrt{3}=0
Subtract x\sqrt{3} from both sides.
3x-x\sqrt{3}=30
Add 30 to both sides. Anything plus zero gives itself.
\left(3-\sqrt{3}\right)x=30
Combine all terms containing x.
\frac{\left(3-\sqrt{3}\right)x}{3-\sqrt{3}}=\frac{30}{3-\sqrt{3}}
Divide both sides by 3-\sqrt{3}.
x=\frac{30}{3-\sqrt{3}}
Dividing by 3-\sqrt{3} undoes the multiplication by 3-\sqrt{3}.
x=5\sqrt{3}+15
Divide 30 by 3-\sqrt{3}.
