\(-3\frac{3}{5}-30\%x=0,45-1\frac{3}{4}x\)

\(-\frac{18}{5}-\frac{3}{10}x=\frac{9}{20}-\frac{7}{4}x\)

\(-\frac{3}{10}x+\frac{7}{4}x=\frac{18}{5}+\frac{9}{20}=\frac{72}{20}+\frac{9}{20}\)

\(\left(-\frac{3}{10}+\frac{7}{4}\right)x=\frac{81}{20}\)

\(\left(-\frac{6}{20}+\frac{35}{20}\right)x=\frac{81}{20}\)

\(\frac{29}{20}x=\frac{81}{20}\)

\(x=\frac{81}{20}:\frac{29}{20}=\frac{81}{20}\cdot\frac{20}{29}=\frac{81}{29}\)

Vậy \(x=\frac{81}{29}\)
