Пошаговое объяснение:

3x-9=18

3х= 18 +9

3х= 27

х= 27 : 3

х=9 подставим во второе уравнение х= 9

x + 3b = - 12​

9 + 3b= -12

3b= - 12 - 9

3b= -21

b= -21 : 3

b= -7

Once upon a time, and in a country long way off, there was a king who was very ill. All the doctors of the court attended him but, in spite of all they could do, he got worse instead, of better. In despair they called in a famous doctor from another country. He came, looked at the king, and said, "There is only one thing that can help you".
"What is that?" said the king.
"You must sleep for one night", said the doctor "in the shirt of a happy man!".
So the king sent two of his chief servants to find a happy man and, when they
had found him, to bring back his shirt.
Well, they went first to the richest man in the city, and asked him if he was a happy man.
How I can be happy when I never know whether my ships are going to be wrecked next day, when thieves are always trying to break into my house.
So they went to the King's Chief Minister, the most powerful man in the country, except for the King. "Are you a happy man?" they said. "Don't be silly" he said. "There's Ruritania threatening to make war on us any day. The workers are always wanting to have more money, and the wealthy wanting to pay less taxes. How do you think a Chief Minister can be a happy man?"
So they went all over the country looking high and low for a happy man but never finding one.
They were returning home, tired and miserable, when they saw a beggar sitting by the roadside. He had made a little fire and was singing merrily as he
watched his supper cooking.
They looked at each other. Had they found what they were looking for? They went up to him and one of them said, "You sound very happy, my friend".
"Of course, I am happy", he said. They could hardly believe their ears. With one voice they said, "We want your shirt!".
The beggar roared with laughter. "I'm sorry, gentlemen", he said "but I haven't.
