Обозначим изначальное число книг на второй полке за х. Так как на первой полке изначально было в 5 раз больше книг, чем на второй, то на второй полке было 5х книг.
С первой полки сняли 16 книг, значит число книг на ней стало
5х - 16; на вторую полку добавили 12 книг, значит число книг на второй полке стало х + 12.
После этого книг на полках стало поровну, составим и решим уравнение:
5х - 16 = х + 12;
4х = 28;
х = 7.
Итак, на второй полке было 7 книг, на первой полке 7 * 5 = 35 книг.
ответ: на первой полке стояло 35 книг, на второй полке 7 книг.
