срочно прошу!!!!!очннь надо сейчас ​

Пошаговое объяснение:

2 - 5(5x + 2) = 5

2 - 25x - 10 = 5

-8 - 25x = 5

25x = -8 - 5

25x = -13

x = -13 : 25

x = -0,52

7 - 5(x - 5) = -3

7 - 5x + 25 = -3

32 - 5x = -3

5x = 32 + 3

5x = 35

x = 35 : 5

x = 7

-1 - 4(-x + 7) = 3

-1 + 4x - 28 = 3

-29 + 4x = 3

4x = 3 + 29

4x = 32

x = 32 : 4

x = 8

2 - 2(3x - 4) = -2

2 - 6x + 8 = -2

10 - 6x = -2

6x = 10 + 2

6x = 12

x = 12 : 6

x = 2
