2k\cos(\alpha )+2=\sqrt{3}\sin(\alpha )
Swap sides so that all variable terms are on the left hand side.
2k\cos(\alpha )=\sqrt{3}\sin(\alpha )-2
Subtract 2 from both sides.
2\cos(\alpha )k=\sqrt{3}\sin(\alpha )-2
The equation is in standard form.
\frac{2\cos(\alpha )k}{2\cos(\alpha )}=\frac{\sqrt{3}\sin(\alpha )-2}{2\cos(\alpha )}
Divide both sides by 2\cos(\alpha ).
k=\frac{\sqrt{3}\sin(\alpha )-2}{2\cos(\alpha )}
Dividing by 2\cos(\alpha ) undoes the multiplication by 2\cos(\alpha ).
