(A) -6
(B) -4
(C) -1/3
(D) 1/3
(E) 3


\((6 + \frac{2}{x})(x - 4) = 0\)
\((6x - \frac{8}{x} - 24 + 2) = 0\)
\((6x - \frac{8}{x} - 22) = 0\)\(6x^2 - 22x - 8 = 0\)
\(6x^2 - 24x + 2x - 8 = 0\)\(6x(x - 4) + 2(x - 4) = 0\)
\((6x+2)(x-4) = 0 => x=4\) or\(-\frac{1}{3}\)

Since x cannot be 4, the other value of x =\(-\frac{1}{3}\) (Option C)
