MrSolution: y^2=+-1? Поправьте опечатку) Я бы дописал еще, что при x=-2y имеем 2y^2=-2, вместо 'не подходит по условию' (у него в условии ничего нет, кроме системы)

person4884: большое спасибо!

перевод
Dear Ed, I am writing this letter to tell you about our trip to Washington, DC. We stayed at our friends. They have their own house in the downtown Washington. I discovered here the streets that go from East to West are named after letters of the alphabet. The streets that go North and South are numbered. The longest and the biggest streets are named after American states. Our host and hostess are very friendly people. They give us advice about places of interest in their city. Every evening we prepare the next day's trip together.
We have already had a trip round the city. It is very green and peaceful. There are a lot of beautiful places where you can relax and enjoy yourself.
I think Washington is a very special city. Most of the people in Washington work for the government and there are many government offices there.
We have already been to the White House. It really is white. You cannot see the part where the president lives and works. It isn't open to the public. But the part we saw was very beautiful. It is maybe one of the most beautiful places in Washington. We saw the library, the Red Room, the Blue Room and the Green Room which had some fantastic old furniture.
I could write more, but I must stop now. We have a lot to do tomorrow as we have to leave early in the morning. We will be home the day after tomorrow and I shall see you then.
Yours sincerely
Bill
