1. а=1 16/7+3/7=3 5/7
2. 8-b=6 5/9-3 4/9
8-b=3 1/9
b=8-3 1/9
b=4 8/9
3.y=9 1/5-7 3/5=46/5-38/5=8/5=1 3/5
4.b-25/11+56/11=7
b+31/11=7
b=7-31/11=77/11-31/11=46/11=4 2/11 вроде бы так:)

1. I woke too early.

2.I have my clothes, my books. I have all my things.

3 My luggage was in Russia.

4 Next day I decided to go to see London.

5 A man came to him and pulled out a gun

6 The man took all the money he had on him.

текс A. And this was the beginning of my problems. I woke up too late. I got to the airport and I saw that I hadn’t taken my passport. I took a taxi home and then back to the airport. I was very upset. I got on the plane. When I came to France, people at the airport told me that my luggage was in China. I didn’t have my clothes. I didn’t have my books. I didn’t have anything.



B. That was too much for me. I decided to leave Paris and go back to England. I phoned my friends in London, asked them to send me some money and I bought a plane ticket for the next flight. Finally, I was back home. When I arrived the travel agent informed me that my luggage was in Paris.



С. When I came to the hotel, they didn’t have a room for me because I hadn’t arrived on time. I went to another hotel where I could spend the night. The night was really hot and the air conditioning was broken. I couldn’t open the window because there was a very busy street outside and the noise was awful.

D. Next day I decided to go to see Paris. When I left the hotel I went straight to see the Eiffel Tower. Before I got there a man came to me and pulled out a gun. He took all the money I had on me.

E. It all started in the morning two months ago. I always wanted to see Paris, the cafes, the Eiffel Tower and Champs Elysees. So I bought a plane ticket to Paris and waited for the day of departure.
