2-(x/41-18/41)=49/41
x/41-18/41=82/41-49/41
x/41=33/41+18/41
x=51

moroka11: Спасибо. но ответ почему-то 15
Аноним: если подставить вместо x 15, то не получим после вычисления 49/41
Аноним: или неправильно записано уравнение, или ошибка в ответе
moroka11: Прошу прощенья!!! В скобочках вместо - стоит +. Тогда должно все сойтись.
Аноним: если стоит +, то тогда меняй везде знак, перед 18/41 и получится в ответе 15
