Пошаговое объяснение:

58+х=61

x = 61 - 58

x = 3

11×х=99

x = 99 : 11

x = 9

963:х=3

x = 963 : 3

x = 321

128-4х=60

4x = 128 - 60

4x = 68

x = 68 : 4

x = 17

х+6х+11=95

7x + 11 = 95

7x = 95 - 11

7x = 84

x = 84 : 7

x = 12

1024:(12+х)=32

12 + x = 1024 : 32

12 + x = 32

x = 32 - 12

x = 20
