Schritte zur Lösung

∣ 7 - 4 b ∣ = 5

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

7 - 4 b = - 5 or 7 - 4 b = 5

7 - 4 b = - 5 or 7 - 4 b = 5

b = \frac{1}{2} or b = 3

2 ∣ x - 6 ∣ + 14 = 38

∣ - 3 - 2 x ∣ = - x

- 4 ∣ 5 x + 4 ∣ + 25 = 9

∣ 3 x - 9 ∣ - 24 = - 12

∣ 8 x - 1 ∣ = 3 x
