Ответ:

Можно решить методом сложения

Объяснение:

Первую часть умножаем на 2

8x+2y=-20

5x-2y=-19

2y сокращается

13x=-39

X=-3

Y=:

4*(-3)+y=-10

Y=-10+12

Y=2

ladawoter: разве y должен быть равен 2?

ladawoter: та не 10 а -10

kibraeva500: спасибо, ступила

  A clever boy

  One day a boy who was cleaning
shoes in the street saw a young man and
said:

“Let me clran your shoes for you”

“No,” the young man answered, “I
don’t want you to clean my shoes”.

«I don’t ask much money for my work,”
said the boy. “I clean shoes very well”.

“No,” the young man said.

“But I want to clean your shoes,”
said the boy. “Don’t
give me any money for my work. I’m going to clean them for nothing.”

“All right,” said the young man,
“clean my shoes.”

     The boy began to clean one of the young
man ‘s shoes. Soon it was shining brightly. Then the boy stopped cleaning and
refused to clean the other shoe.

“you must
give me some money for my work if you want me to clean the other shoe,” he
said.

“No,” the
young man refused and went away. But soon he understood that it is not good to
be in the street with one shoe clean and the other shoe not clean. The
people in the street looked at him and laughed. He went back to the boy , gave him the
money and told him to clean other shoe. In
a very short time his shoes shone brightly.
