Identify the equation which arises from the following equation using an optimal
substitution.
\[
\mathop{\mathrm{tg}}\nolimits x + \frac{2\sqrt{3}}{3}=\mathop{\mathrm{cotg}}\nolimits x
\]
\(\sqrt{3}t^{2} +2t -\sqrt{3}= 0\)
\(t^{2} +2\sqrt{3}t-1= 0\)
\(3t^{2} -2\sqrt{3}t +{3}= 0\)
\(\sqrt{3}t^{2} +t +2\sqrt{3}= 0\)
