Son ecuaciones de 1er Grado...
g) 11 - 6k = - 13
11 + 13 = 6k → 24 = 6k
∴ k = 4
h) 21 = 12z - 15
21 + 15 = 12z → 36 = 12z
∴ z = 3
i) - 7x - 15 = 20
- 20 - 15 = 7x → - 35 = 7x
∴ x = - 5
j) 3x + 3 = 108
3x = 108 - 3 → 3x = 105
∴ k = 35
k) 2x + 15 = 61
2x = 61 - 15 → 46 = 2x
∴ x = 23
l) - 5x + 600 = 425
600 - 425 = 5x → 175 = 5x
∴ x = 35
