Respuesta :

x + 8 = 9

x = 9 - 8

x = 1

2x + 5 = 9x - 7

7 + 5 = 9x - 2x

12 = 7x

12 / 7 = x

x = 12 / 7

7x + 20 = - x - 9

7x + x = - 20 - 9

8x = - 29

x = - 29 / 8

x - 2 = 20 - 8x

x + 8x = 2 + 20

9x = 22

x = 22 / 9

x - 2 = 5x + 9

x - 5x = 2 + 9 - 4x = 11

x = 11 / - 4

x = - 11 / 4

x - 9 = 20x - 6

x - 20x = 9 - 6 - 19x = 3

x = 3 / - 19

x = - 3 / 19

4x - 9 = - 9 - x + x

4x - 9 = - 9

4x = 9 - 9

4x = 0

x = 0 / 4

x = 0

10x - 10x + 8 = - x - 1

8 = - x - 1

x = - 8 - 1

x = - 9.
