(2.61-4х):0.03+4.6=90

(2.61-4х):0.03=90-4.6

(2.61-4х):0.03=85.4

2.61-4х=85.4*0.03

2.61-4х=2.562

-4х=2.562-2.61

-4х=-0.048

х=-0.048:(-4)

х=0.012.

New York and Toronto may think they are more cosmopolitan, but London in the 21st century is certainly the most diverse city ever. This is one of the reasons why it was chosen to host the 2012 Olympic Games. More than 300 languages are spoken by the people of London, and it has 50 nationalities with populations of more than 10,000. Why is this? Firstly, London is a place of business. Londoners have the fewest bank holidays in Europe and work the longest hours. People come for jobs and money. But that is not why they stay. Language is one reason. Fluency in English is a great gift for their children. Another surprising reason is the character of the London people. They are not as friendly as some other nationalities. But this has advantages – people leave you alone, and you are free to live your own life. Finally, the most delicious reason is – food. You can have dinner in more than 70 different nationalities of restaurant any night of the week. Londoners’ enthusiasm for foreign food creates thousands of jobs for new communities. All Londoners, old and new, have the same principles. They work hard, love their children, and move out of the city centre as soon as they can afford it!
