Ответ:

10/15 + (5/15 - x) =14/15

10/15 + (1/3 - x) = 14/15

10/15 + 1/3 - x = 14/15

1 - x = 14/15

-x = - 1/15

x = 1/15

/ - дробь

1 ТЕКСТ -  Family  means a lot to me. It's not just two three or seven people living together but a unity of people who support each other in different situation. Anything can happen in this life but i know that the only people who will always love and understand me are my family. Blood is thicker than water. That's why family is much more important to me than friends. Friends can betray you. There are lots of books and films about this. They can envy your success at school and your success with girls and even your cool jeans or a bike can make them feel jealous . It doesn't matter that i don't have many friends. And if i get into trouble, the people i ask for advice are my parents



2 ТЕКСТ - Friends are everything to me. Life isn't worth living without friends. My family... they don't care about me, and frankly speaking , i don't care much about them either. The only things they care about are their jobs and making money. Even my grades at school don't worry them much. Sometimes they ask me about my progress, but I'm never sure if they hear my answer. I would feel absolutely lonely if I did not have friends. We often gather at my place or somewhere else to speak about life, listen to music and have fun. Sometimes we quarrel, but I don't believe that my friends mean to hurt me. Life is cool with them.



3 ТЕКСТ  -  I think I'm
very lucky. I have a family that loves me and friends I enjoy spending time with. My parents and I are people of different generations, so we don't see the world in the same way. But I know they wish me well and I appreciate their advise. (Though sometimes I ignore it and forget about it) They don't like all of my friends, but they don't just say "no". They try to explain their point of view, and sometimes I find their arguments quite convincing. I agree that not all people you go out with can be called friends. Real friends are very rare and you should sherish them. And if you happen to find them, take care of them, never hurt them and try not to lose them.
