В таком случае речь идёт о сравнении выражений:
1) Оставшиеся в конце тетради в линейку:
16-x, где x - это количество израсходованных тетрадей в линейку
2) Оставшиеся в конце тетради в клетку:
23-(x+9)=14-x.
Что больше? Очевидно, 16-x больше, чем 14-x. Причём больше на 2 тетради.
ответ: тетрадей в линейку осталось на 2 больше, чем в клетку.
