Question

92 : (3 * b + 5 ) = 4 (240 : x + 48) : 26 = 2​

Answer 1

3 * b + 5 = 92 : 4  

3 * b + 5 = 23

3 * b = 23 - 5

3 * b = 18

b = 18 : 3

b = 6

Проверка

92 : (3 * 6 + 5) = 4

92 : (18 + 5) = 4

92 : 23 = 4

4 = 4

(240 : x + 48) : 26 = 2

240 : x + 48 = 2 * 26  

240 : x + 48 = 52

240 : x = 52 - 48

240 : x = 4

x = 240 : 4  

x = 60

(240 : 60 + 48) : 26 = 2

(4 + 48) : 26 = 2

52 : 26 = 2

2 = 2.
