Объяснение:

Пусть x - количество примеров на самостоятельной

\frac{x - 3}{x - 10} = 2

x - 3 = 2(x - 10)

x - 3 = 2x - 20

x = 17

Too Well (After O’Henry)
Miss Carington was a famous actress. She began her life in a small village named Cranberry. But that was long ago. Now she was to perform the leading part in a new comedy.
A capable young actor Highsmith by name dreamt of being Miss Carington’s partner in the new play. He told it to the manager. The manager explained to the young actor that if he wanted to play the part he must persuade Miss Carington to accept him as a partner.
The young actor knew very well that it was the part of a young farmer. The next day he went to Cranberry where he stayed for three days and gathered much information about the life and the people of that small village. Then he returned from the village and went to one of the restaurants where actors usually gathered after the performance.
He saw a small party sitting at the table. The star of that party was Miss Carington.
She noticed a poorly dressed man entered the restaurant. He approached the famous actress, greeted her and told her much interesting news about her relatives and friends from Cranberry. The way he spoke made her believe every word he said. She was sure he was a farmer.
In the end he told the famous actress that her mother wanted to see her again before she died. Then he gave her a rose he picked up from a bush in front of her house in Cranberry.
Miss Carington was so touched that she couldn’t help crying. She thanked the young man and invited him to see her again at the hotel before he left the city.
The next morning the young actor dressed in the latest fashion went to the hotel. He was sure Miss Carington would agree to take him as a partner in the play if he told her everything.
To his surprise he was told that Miss Carington had left for her native village forever. Highsmith realized that he had acted too well.
