Answer 1

Respuesta:

9, 10, 5, 10, 2, 7, 8, 7, 5, 6

Explicación paso a paso:

5x + 4 = 49

5x = 49 -4

5x = 45

x = 9

3x + 1 = 31

3x = 31 - 1

3x = 30

x = 10

7x + 1 = 36

7x = 36 - 1

7x = 35

x = 5

9x + 1 = 91

9x = 91 - 1

9x = 90

x = 10

2x + 9 = 13

2x = 13 - 9

2x = 4

x = 2

8x + 8 = 64

8x = 64 - 8

8x = 56

x = 7

3x + 3 = 27

3x = 27 - 3

3x = 24

x = 8

3x + 9 = 30

3x = 30 - 9

3x = 21

x = 7

x + 3 = 8

x = 8 - 3

x = 5

4x + 2 = 26

4x = 26 - 2

4x = 24

x = 6
