x+2=x\times 2-\sqrt{3}x
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by x.
x+2-x\times 2=-\sqrt{3}x
Subtract x\times 2 from both sides.
-x+2=-\sqrt{3}x
Combine x and -x\times 2 to get -x.
-x+2+\sqrt{3}x=0
Add \sqrt{3}x to both sides.
-x+\sqrt{3}x=-2
Subtract 2 from both sides. Anything subtracted from zero gives its negation.
\left(-1+\sqrt{3}\right)x=-2
Combine all terms containing x.
\left(\sqrt{3}-1\right)x=-2
The equation is in standard form.
\frac{\left(\sqrt{3}-1\right)x}{\sqrt{3}-1}=-\frac{2}{\sqrt{3}-1}
Divide both sides by -1+\sqrt{3}.
x=-\frac{2}{\sqrt{3}-1}
Dividing by -1+\sqrt{3} undoes the multiplication by -1+\sqrt{3}.
x=-\left(\sqrt{3}+1\right)
Divide -2 by -1+\sqrt{3}.
