1) Сначала выразим (36-х:4). Получаем 36-х:4=240/8

36-х:4=30

Выразим -х/4: -х/4=30-36

-х/4=-6

-х=-6*4

-х=-24

х=24

Ответ: 24

2)  Выразим выражение с у: 540:(у+12)=18+9

540:(у+12)=27

у+12=540:27

у+12=20

у=20-12

у=8

Ответ:8

John Ronald Reuel Tolkien was English, but he was born in South Africa in 1892.
Both his parents died when he was a boy, so John went to live with an aunt in
England. After he left school, he went to Oxford University and studied English. Then
he got a job as a teacher at the university,
Tolkien had four children and he often told them stories. They really enjoyed one
story. It started : "In a hole in the ground lived a hobbit ...". This story became
Tolkien's first book, The Hobbit. He later wrote The Lord of Rings. Both books were
popular, especially in the USA. Tolkien became rich and famous, but he hated being
well known. Tolkien created an imaginary world called “Middle Earth” and special
languages for his stories.
He died in 1973. Thirty years later, the New Zealand film director Peter
Jackson made three films of The Lord of the Rings. They were big hits all over the
world
