Explicación paso a paso:
C. 32 = 6x - 7 . (-2)
32 = 6x + 14
- 14 + 32 = 6x
18 = 6x
18/6 = x
3 = x
D. x + 7x + 12 = - 13 . 4
8x + 12 = - 52
8x = - 52 - 12
8x = - 64
x = - 64/8
x = - 8
E. - 8 . 6 - 3 . 14 = 12x + 6x
- 714 = 18x
- 714/-18 = x
39,666 = x
F. x - 12 - 6x = - 18 + 6
-12 -5x = - 12
5x = -12 + 12
5x = 0
x = 5 . 0
x = 0
