Question

помогите решить уровнения

Answer 1

Ответ:

Пошаговое объяснение:

3x - 18 = 0

3x = 18

x = 18 : 3

x = 6

20x + 4 = 0

20x = -4

x = -4 : 20

x = -0,2

-16x - 32 = 0

-16x = 32

x = -32 : 16

x = -2

-64x + 8 = 0

-64x = -8

x = 8 : 64

x = 0,125

-2 - 34x = 0

-34x = 2

x = -2 : 34

x = -1/17

75 + 3x = 0

3x = -75

x = -75 : 3

x = -25
