3 года Лесе. Вот так.Сейчас Лесе 3 года. Так как из условия можно понять, что через 3 года, Леся будет вдвое старше, чем 3 года назад (то есть сейчас). Выходит уравнение:

Х=3

“I’m afraid not,” Mummy said. “The weather is awful.”
Millie and Billy looked out of the window. It was windy and it was raining.
“It’s very cold too,” Mummy said. “So you’ll stay at home.”
“What can we do then?” Billy asked.
“You can have indoor fun,” Mummy said. “Think of things that will be fun to do indoors and do them.”
So, that is what they did.
They draw some pictures and coloured them. Millie did a picture of an elephant and Billy did one of a bear.
Then they looked all around the house for secret places. They couldn’t find one but what they found was a little toy dinosaur behind a cupboard in the spare room. The toy was dusty, the children washed it and it was as good as a new .
After that they made a camp in the living room. They took the dinosaur into the camp.
