Explicación paso a paso:

1) 5x + 4 = 49

5x = 49 - 4

5x = 45/5

X = 9

2) 3x + 1 =31

3x = 30

X = 10

3) 7x + 1 = 36

7x = 35

X = 5

4) 9x + 1 = 91

9x = 90

x = 10

5) 2x + 9 = 13

2x = 4

X = 2

6) 8x + 8 = 64

8x = 56

X = 7

7) 3x + 3 = 27

3x = 24

x = 8

8) 3x + 9 = 30

3x = 21

x = 7

9) 1x + 3 = 8

1x = 5

X = 5

10) 4x + 2 = 26

4x = 24

x = 6
