La primera ecuación :

1.

- 2x + 43 = 3 = = = >x = - 20

2.

- 7x + 60 = 11 = = = = > x = - 7

3.

- 5x - 10 = 15 = = > x = 5

4.

- x + 7 = 18 = = = > x = 11

5.

- x + 34 = 72 = = = > x = 38

8.

- 10n + 110 = 10 = = = > x = - 10

9.

- 17z + 324 = 35 = = = > x = - 17

10.

- 19 + 8t = 83 = = = > x = 8

11.

- 35 + 7x = 0 = = = > x = - 5

12.

- 54 + 9x = 0 = = = > x = - 6

Todas están comprobadas y dan un resultado preciso.
