Вероника8: Спасибо, но в моем решении другой ход. Мне нужно найти ошибку именно в моем решении. Так, как у вас фотоматч решает. Я это видела.

ara94: в первом надо то, что в знаменателе, поменять знак. Там 2-х, меняете и х-2, и перед дробью -.

ara94: потому в 4 ряду не 3х+6, а -3х-6

Task 3

Swift and his servant

Jonathan Swift, a famous English writer, was one day travelling on horseback with a servant. The weather was bad; it was raining and the roads were muddy. In the evening the two men came to an inn. Before going to bed, Swift told his servant to clean his boots as they were dirty. But the servant was very lazy and did not do what his master had said.
The next morning when Swift saw the dirty boots, he asked the servant why he had not executed the order. ”The roads are muddy. What is the use of cleaning the boots now? They will soon be dirty again,” the servant answered.
Swift didn’t say anything and soon told the servant to get ready because they would start at once. But the servant looked very displeased and said that he had not eaten his breakfast yet.
Swift answered that they would go without any breakfast.
”What is the use of eating now? You will be hungry again”, he said.
