5x + 11 = 2x - 13

5х-2х=-13-11

3х=-24

х=-24/3

х=-8

2(2 - y) = y - 5

4-2у=у-5

-2у+у=-9

-у=-9

у=9

Прочитайте тексты и установите соответствие между текстами и их заголовками: к каждому тексту, обозначенному буквами А–G, подберите соответствующий заголовок, обозначенный цифрами. Используйте каждую цифру только один раз. В задании есть один лишний заголовок.

1. Generation gap
2. Attractive but unhealthy
3. Youth movements and societies
4. Always busy
5. Conflicts with friends
6. Parents’ ambitions
7. Are teenagers happy?
8. They want to earn and spend

A.
The age between 14 and 17 is often considered to be one of the best periods in a person’s life. Grown-ups remember it with excitement and happiness. The wish they were teenagers again. However, most teenagers won’t agree with this point of view if they were asked. They're sure that they are facing a lot of difficult problems and that's quite true.

B.
Smoking has become one of the most important problems for modern teenagers. About 40 percent of teenagers are attracted by the bright cigarette advertisement. It seems they just don't realize the harm it does to their health, because advertisements show smoking as something positive. They really believe that smoking will make them look like they're cool and grown-up.

C.
In fact, teenagers have got a lot of work. They're busy with their studies, household chores, some of them have jobs. They can’t even find a moment to entertain themselves at times. It’s a more serious problem especially for those who are responsible and want to be successful students and good children.

D.
The problem number one for most young people is between fathers and sons. All young people want to be independent, they want their parents to listen to their opinion. As for parents, they want to control their children’s lives. At the same time some parents can’t find a common language with their kids and simply don’t pay enough attention to them.

E.
They say that all teenagers want to have a lot of money to dress well, to go to theatres, to visit foreign countries, to eat what they want and to buy books. But how can they do all these things? They have to get some money and it’s possible to do it. Some teenagers wash cars, others sell newspapers, help elderly people and babysit.

F.
School ages are also very difficult. Children are always stressed because of their marks at school. It seems to teenagers that they do a lot of homework, but mothers and fathers are never satisfied. They want their children to have the highest marks at school. Teenagers do their best, but adults are never happy. They always want more.

G.
There are many organizations which unite young people. Teenagers get together because of common interests and beliefs. Members of every organisations have their own attitudes to the world. There are some informal clubs, for example: emos, hippies, panks, and so on. However, some teenagers choose to join more serious groups like Greenpeace.
