8,3-2,1 = 2*(1,5x+11,8)

6,2 = 3x+23,6

3x = 6,2-23,6

3x = -17,4

x = -5,8

Пожалуйста!! Помогите!! Очень надо!!! Reading A mysterious robbery Mr Fergus Dilger turned up at his toy shop in Fareham, England on Monday morning to find that he had been robbed! Someone had entered the shop at some point between the moment he closed at 5.30 p.m. on Saturday, and the time he arrived on Monday morning. The mystery was that there had been money in the shop, and it was still there. The thieves also hadn’t stolen his computer or any of the expensive computer games in the store. The only thing that was missing was about twenty packets of children’s cards. These come from a game with pictures of monsters, which has been incredibly popular since it went on sale last year. Mr Dilger spoke to me by phone this morning. “If they had stolen something valuable, I would have called the police” he said, “but this is crazy!” Later in the day, the crime was solved by video cameras in the street outside the shop. They had recorded a pair of people about 1½ metres tall climbing through a window at the back of the shop late on Saturday evening. “It seems clear that some children saw the open window and decided to steal the cards for their favourite game” said a police officer this afternoon, after we had contacted them about the events. “But because Mr Dilger said he wouldn’t complain to us, we haven’t begun an investigation. Nevertheless, we will visit all schools in the local area to remind children that a crime is a crime.” Mr Dilger told us that his shop would be open throughout the week, as usual. Read the text. Put the events in order 0–6. A reporter spoke to Mr Dilger. The thieves took the cards. Mr Dilger left a window open. Mr Dilger discovered the crime. The thieves were filmed. The children’s card game went on sale. The police learned about the crime. Read the text again. Are the sentences True or False? If you don’t have enough information, write ‘Not stated’. 1. Mr Dilger saw how the crime was happening. 2. The thieves took a lot of cash. 3.The cards show hundreds of different monsters 4. Mr Dilger phoned the police. 5. The crime happened at the weekend. 6. There were two criminals. 7. The police have been visiting lots of schools.
