Решение и ответ:
[tex]\displaystyle \frac{{3x-5}}{5}=\frac{{4-2x}}{6}[/tex]
[tex]\displaystyle 5\cdot\left({4-2x}\right)=6\cdot\left({3x-5}\right)[/tex]
[tex]\displaystyle 20-10x=18x-30[/tex]
[tex]\displaystyle -10x-18x=-30-20[/tex]
[tex]\displaystyle -28x=-50[/tex]
[tex]\displaystyle x=-50\div(-28)[/tex]
[tex]\displaystyle x=\frac{{25}}{{14}}=1\frac{{11}}{{14}}[/tex]
