Explicación paso a paso:

9 + 2x – 1 = 6x

9 - 1 = 6x - 2x

8 = 4x

8/4 = x

2 =x

7x – x + 5 = 17

7x - x = 17 - 5

6x = 12

X = 12/6

X =2

3x – 11 + 2x = 29

3x + 2x = 29 + 11

5x = 40

X = 40/5

X = 8

3x + 9 = x + 15

3x - x = 15 - 9

2x = 6

X = 6/2

X = 3

7x – 3 = 3x + 13

7x - 3x = 13 + 3

4x = 16

X = 16/4

X = 4

7 + 2x – 5 = 4x

7 - 5 = 4x - 2x

2 = 2x

2/2 = x

1 = x

6x + 5 = x + 40

6x - x = 40 - 5

5x = 35

X = 35/5

X = 7

6x – 15 + x = 13

6x + x = 13 + 15

7x = 28

X = 28/7

X = 4

14 – 3x + 2 = 5x

14 + 2 = 5x + 3x

16 = 8x

16/8 = x

2 = x

3x – 11 + 2x = 29

3x + 2x = 29 + 11

5x = 40

X = 40/5

X = 8
