Объяснение:

Раскрываем скобки:

6а + 6*3,4 - 12 = 6а + 20,4 - 12 = 6а +8,4.

Если выражение приравнять нулю (т.е., если это уравнение), то:

6а + 8,4 = 0
6а = - 8,4

а = - 8,4/6

а = - 1,4

Evergrowing and mobile
Here, mobility is not a luxury – it is a downright necessity. Pedestrians are treated with great suspicion and can be stopped by the police as you only ever walk the short distance from the car park to the entry of a hotel or a bar. Otherwise, the absolute minimum is two wheels (such as those of a Harley Davidson, as preferred by Arnold Schwarzenegger). L.A. is a city of car drivers. It does not have to be a Rolls of course. Yet, the fact is there are more cars bearing “Emily” on the tips of their hoods than in any other city in the world. Or ultra-low Thunderbird Convertible used by the Chicano kids in South Central when they are practicing drive-by-shooting with pump guns from the comfort of their cars. But do not be afraid: L.A. is less dangerous than, say, Washington. And even downtown you are perfectly safe – provided you stay in your car.
Los Angeles is not only mobile city because of the large distances. It is still a town of adventurers as in the days of the Gold Rush. And adventurers have got to be flexible, ready to grab every chance that passes them by. Here, an ambitious young body builder from Austria is able to make the big time as mega film star and go on to become multi-millionaire. In fact, he has even managed to marry into the elegant (East Coast) Kennedy Clan. Even Angelenos who have only been in the city for a few weeks know that the streets are not paved with millions. Everything must stay in motion. If you stand still you are as good as dead; never-сeasing change is an everyday occurrence. Angelenos do not bemoan failures but simply discount them. All that counts is the future.
And indeed, nothing seems to be impossible at this gigantic vanity fair. The Angelenos are passionate actors regardless of their class or ethnic origins. They have little regard for such “European” values as ”style” or ”taste”. Their credo is simple: be what you are!​
