посчитайте надо решить уравнением ​

16x + 41 = 2x + 55

16x - 2x = 55 - 41

14x = 14

x = 14:14

x = 1

x + 5 = 2x + 1

2x - x = 5 - 1

x = 4

18 + 3x = x + 14

3x - x = 14 - 18

2x = -4

x = -4 : 2

x = -2

21x + 76 = 2x + 38

21x - 2x = 38 - 76

19x = -38

x = -38 : 19

x = -2

10x - 16 = 2x + 4

10x - 2x = 4 + 16

8x = 20

x = 20:8

x = 2,5

2(x + 6) = 4x + 4

2x + 12 = 4x + 4

4x - 2x = 12 - 4

2x = 8

x = 8 : 2

x = 4

3(x + 2) = 10x - 15

3x + 6 = 10x - 15

10x - 3x = 6 + 15

7x = 21

x = 21 : 7

x = 3

10(x + 1) + 11(x - 2) = 9

10x + 10 + 11x - 22 = 9

21x - 12 = 9

21x = 9+12

21x = 21

x = 21:21

x = 1

16x - 5 -(3x - 5) = 26

16x - 5 - 3x + 5 = 26

13x = 26

x = 26:13

x = 2

3(3x - 3) + 3(3 - 3x) + x = 10

9x - 9 + 9 - 9x + x = 10

x = 10
