Solve the following equation in the set of complex numbers. (Solve the equation by substitution.)

(3 x + 2)^{4} - 81 = 0

{- \frac{5}{3}; \frac{1}{3}; - \frac{2}{3} + i; - \frac{2}{3} - i}

{- \frac{5}{3}; \frac{1}{3}; \frac{2}{3} + i; \frac{2}{3} - i}

{\frac{5}{3}; - \frac{1}{3}; - \frac{2}{3} + i; - \frac{2}{3} - i}

{\frac{5}{3}; - \frac{1}{3}; \frac{2}{3} + i; \frac{2}{3} - i}
