Question

Решите уровнение

540/(у+12)-9=18

Answer 1

540 / ( Y + 12 ) = 18 + 9 
540 / ( Y + 12 ) = 27 
Y + 12 = 540 : 27 
Y + 12 = 20 
Y = 8

Answer 2

540/(у+12)-9=18
540/(у+12) = 18 + 9
540/(у+12) = 27
у+12 = 540 : 27
у+12 = 20
у = 20 - 12
у = 8
---------------------------------
540/(8+12)-9=18
540/20-9=18
27-9=18
18=18
