Question

64-(3n+8n+n):40=37 уравнение

Answer 1

64-(3n+8n+n):40=37

(3n+8n+n):40= 64 - 37

12n : 40 = 27

12n = 27* 40

12n = 1080

n = 90

Проверка:

64 - (3 * 90 + 8 * 90 + 90) : 40 = 64 - 1080 : 40 = 64 - 27 = 37

37 = 37

 

Answer 2

64-(3п+8п+п):40=37

(3n+8n+n):40=64-37

12п:40=27

12п=27*40

12п=1080

п=1080:12

п=90
