Преобразуем обычную дробь 6,5 в обычную 13/2, после 13/2
3/2 сокращаем двойки убираются получается 13/3
х-3/х-2=13/3
упрощаем уравнение путем перекрестного умножения
3(х-3)=13(х-2)
умножаем первую часть 3*х и 3*(-3)=3х-9=13(х-2)
так же делаем со второй скобкой 13*х и 13*(-2)= 3х-9=13х-26
переносим 13х в левую часть и меняем знак если был + то будет -. 3х-13-9=-26. Приводим подобные члены -10х=-26+9. -10х=-17
далее разделим обе стороны на -10. получится х=17/10-1,7
