Пошаговое объяснение:

7m + 1 = 8m + 9

8m - 7m = 1 - 9

m = -8

5x - 8 = 4 - 7x

5x + 7x = 4 + 8

12x = 12

x = 12 : 12

x = 1

14 + 5x = 4x + 3x

14 + 5x = 7x

7x - 5x = 14

2x = 14

x = 14 : 2

x = 7

36 + 2x = 5x + 12

5x - 2x = 36 - 12

3x = 24

x = 24 : 3

x = 8

3x + 5 = 8x - 15

8x - 3x = 5 + 15

5x = 20

x = 20 : 5

x = 4

-2x + 16 = 5x + 30

5x + 2x = 16 - 30

7x = -14

x = -14:7

x = -2

28 - 32x = -48 - 50x

50x - 32x  = -48 - 28

18x = -76

x = -76 : 18

x = -4 2/9

11a - 7 = -22 + 5a

11a - 5a = -22 + 7

6a = -15

a = -15 : 6

a = -2,5

56 + 6x = 3x - 13

6x - 3x = -13 - 56

3x = -69

x = -69 : 3

x = -23

7a - 11 = 10a + 16

10a - 7a = -11 - 16

3a = -27

a = -27 : 3

a = -9
