Espero y te ayude.

13x + 6 - 7x = 2x - 10

13x - 7x - 2x = - 10 - 6

4x = - 16

x = - 16 / 4

x = - 4

- 4x + 5 - 6x = - 15

- 4x + 6x = - 15 - 5

2x = - 20

x = - 20 / 2

x = - 10

8 + 5x + 3 = 7x - 1

5x - 7x = - 1 - 3 - 8

- 2x = - 12

x = - 12 / - 2

x = 6

3x - 7x +2x = 13

- 2x = 13

x = 13 / - 2

x = - 6.5
