Schritte zur Lösung

∣ 3 + 5 x ∣ = 7

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

3 + 5 x = - 7 or 3 + 5 x = 7

3 + 5 x = - 7 or 3 + 5 x = 7

x = - 2 or x = \frac{4}{5}

- 2 ∣ x - 5 ∣ - 11 = - 29

∣ 2 y + 8 ∣ + 7 = 1

∣ 3 x + 0.1 ∣ = 6

∣ 2 b + 3 ∣ - 7 = 8

∣ x + 19 ∣ = 25
