Question

2. Упрости уравнения. y (36: 6) = 42 630:9+ a= 240 40:5-x=24 13-6-x=1 46.​

Answer 1

Ответ и Пошаговое объяснение:

y·(36:6) = 42

y·6 = 42

y = 42:6

y = 7.

630:9+a= 240

70+a= 240

a = 240-70

a = 170.

40:5-x = 24

8-x = 24

-x = 24-8

-x = 16

x = -16.

13-6-x = 146

7-x = 146

-x = 146-7

-x = 139

x = -139.
