10\sqrt{3}-x\sqrt{3}+2\left(10-x\right)=\sqrt{3}x
Use the distributive property to multiply 10-x by \sqrt{3}.
10\sqrt{3}-x\sqrt{3}+20-2x=\sqrt{3}x
Use the distributive property to multiply 2 by 10-x.
10\sqrt{3}-x\sqrt{3}+20-2x-\sqrt{3}x=0
Subtract \sqrt{3}x from both sides.
10\sqrt{3}-2x\sqrt{3}+20-2x=0
Combine -x\sqrt{3} and -\sqrt{3}x to get -2x\sqrt{3}.
-2x\sqrt{3}+20-2x=-10\sqrt{3}
Subtract 10\sqrt{3} from both sides. Anything subtracted from zero gives its negation.
-2x\sqrt{3}-2x=-10\sqrt{3}-20
Subtract 20 from both sides.
\left(-2\sqrt{3}-2\right)x=-10\sqrt{3}-20
Combine all terms containing x.
\frac{\left(-2\sqrt{3}-2\right)x}{-2\sqrt{3}-2}=\frac{-10\sqrt{3}-20}{-2\sqrt{3}-2}
Divide both sides by -2\sqrt{3}-2.
x=\frac{-10\sqrt{3}-20}{-2\sqrt{3}-2}
Dividing by -2\sqrt{3}-2 undoes the multiplication by -2\sqrt{3}-2.
x=\frac{5\sqrt{3}+5}{2}
Divide -10\sqrt{3}-20 by -2\sqrt{3}-2.
