64Х-17,6=105Х-79,1 56≠0

64Х-105Х=-79,1+17,6

-41Х=-61,5

Kingdom of the Birds Before the first human beings arrived, New
Zealand was inhabited by birds. There were over 160 different species.
With few natural enemies, most of these birds gradually lost their
ability to fly. They evolved special ways of living: some were very tall
and ate leaves off trees, while others grazed like sheep. Today, only a
few of New Zealand's flightless birds survive. One is the kiwi, which
is about the size of a duck. The kiwi is the national bird and emblem.
New Zealanders often call themselves 'Kiwis'. The other surviving
flightless birds are the takehe, which is bright blue and green, and the
kakapo. Unfortunately, there are only about 50 kakapo left. Most of New
Zealand's unique birds and many of its native seals and fish have
become extinct in the last five hundred years.Прошу, надо задать 6 вопросов к тексту.Отмечу ,как лучший ответ.
