Математика 6 класс 1127 номер ​

Пошаговое объяснение:

1)

-5x = 30

x = 30:(-5)

x = -6

2)

-0,8x = -5,6

x = -5,6:(-0,8)

x = 7

3)

-7x = 4

x = 4:(-7)

x = -(4/7)

4)

-6x = -8

x = -8:(-6)

x = 1 2/3

5)

(2/3)x = -(3/8)

x = -(3/8):2/3

x = -(3/8)*3/2

x = -(9/16)

6)

40,5 : x = -9

x = 40,5 :(-9)

x = -4,5

7)

-(32/63) : x = 8/21

x = -(32/63) : 8/21

x = (-32/63) * 21/8

x = -(4/3)

x = -1 1/3

8)

x : 2/7 = -1,4

x = -1,4 * 2/7

x = -(14/10) * 2/7

x = -(2/5)
