`Answer:`

\(3.\left(3x.2\right)+50\%=-\frac{9}{4}\)

\(\Leftrightarrow3.\left(3x.2\right)+\frac{1}{2}=-\frac{9}{4}\)

\(\Leftrightarrow3.\left(3x.2\right)=-\frac{9}{4}-\frac{1}{2}\)

\(\Leftrightarrow3.\left(3x.2\right)=-\frac{11}{4}\)

\(\Leftrightarrow3x.2=-\frac{11}{4}:3\)

\(\Leftrightarrow3x.2=-\frac{11}{12}\)

\(\Leftrightarrow x.2=-\frac{11}{12}:3\)

\(\Leftrightarrow x.2=-\frac{11}{36}\)

\(\Leftrightarrow x=-\frac{11}{36}:2\)

\(\Leftrightarrow x=-\frac{11}{72}\)
