Answer 1

5x + 4 = 49

5x + 4 - 4 = 49 - 4

5x = 45

x = 9

3x + 1 = 31

3x + 1 - 1 = 31 - 1

3x = 30

3x/3 = 30/3

x = 10

7x + 1 = 36

7x + 1 - 1 = 36 - 1

7x = 35

= 7x/7 = 35/7

x = 5

9x + 1 = 91

9x + 1 - 1 = 91 - 1

9x = 90

9x/9 = 90/9

x = 10

2x + 9 = 13

2x + 9 - 9 = 13 - 9

2x = 4

2x/2 = 4/2

x = 2

8x + 8 = 64

8x + 8 - 8 = 64 - 8

8x = 56

8x/8 = 56/8

x = 7

3x + 3 = 27

3x + 3 - 3 = 27 - 3

3x = 24

3x/3 = 24/3

x = 8

3x + 9 = 30

3x + 9 - 9 = 30 - 9

3x = 21

3x/3 = 21/3

x = 7

1x + 3 = 8

1x + 3 - 3 = 8 - 3

x = 5

4x + 2 = 26

4x + 2 - 2 = 26 - 2

4x = 24

4x/4 = 24/4

x = 6
