Schritte zur Lösung

∣ 9 x + 7 ∣ = 8

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

9 x + 7 = - 8 or 9 x + 7 = 8

9 x + 7 = - 8 or 9 x + 7 = 8

x = - \frac{5}{3} or x = \frac{1}{9}

7 - 3 ∣ x + 6 ∣ = 7

∣ 2 x + 4 ∣ + 9 = 15

4 ∣ 3 - 2 x ∣ - 1 = 47

3 ∣ y - 2 ∣ - 12 = 0

∣ 3 x + 2 ∣ = 6
