Х/Х-5-Х-6/Х-5=1/2

X+5=-12

x=-17

дробь -17/-12 или 17/12

ДАААМ 25 БАЛЛОВ!!!
Gemma (was able, could, managed) paint really well when she was only four years old. In fact she was so good that her parents (could, able to, managed) to get one of her paintings into a famous art exhibition. Her talents surprised her parents because they (didnt managed, couldnt, werent able) to paint at all. They (couldnt,werent able, didnt managed) understand why Gemma was so talented. When she was ten, she started selling portraits of people and animals online and (can, was able, could) to make quite a lot of money. However, although she was successful as an artist, she never (managed, was able, could) to do her homework and she had to stay down in her class a year. Now she has extra lessons and thinks she will (be able to, managed, can) improve her schoolwork enough so that she can join her old class again. дал бы больше баллов но нету
