\(\frac{1}{2}\left(6x-5\right)-5x=1\frac{3}{5}\)
\(\Rightarrow6x.\frac{1}{2}-5.\frac{1}{2}-5x=\frac{8}{5}\)
\(\Rightarrow3x-\frac{5}{2}-5x=\frac{8}{5}\)
\(\Rightarrow3x-5x=\frac{8}{5}+\frac{5}{2}\)
\(\Rightarrow-2x=\frac{16}{10}+\frac{25}{10}\)
\(\Rightarrow-2x=\frac{41}{10}\)
\(\Rightarrow x=\frac{41}{10}:-2\)
\(\Rightarrow x=\frac{41}{10}.\frac{1}{-2}\)
\(\Rightarrow x=-\frac{41}{20}\)
Vậy \(x=-\frac{41}{20}\)
Chúc bạn học tốt !!!!
