2=\sqrt{3}-a
Add 0 and 2 to get 2.
\sqrt{3}-a=2
Swap sides so that all variable terms are on the left hand side.
-a=2-\sqrt{3}
Subtract \sqrt{3} from both sides.
\frac{-a}{-1}=\frac{2-\sqrt{3}}{-1}
Divide both sides by -1.
a=\frac{2-\sqrt{3}}{-1}
Dividing by -1 undoes the multiplication by -1.
a=\sqrt{3}-2
Divide 2-\sqrt{3} by -1.
