Schritte zur Lösung

∣ 9 - 4 x ∣ = 7

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

9 - 4 x = - 7 or 9 - 4 x = 7

9 - 4 x = - 7 or 9 - 4 x = 7

x = \frac{1}{2} or x = 4

∣ 4 z + 3 ∣ + 5 = 8

3 ∣ x - 2 ∣ + 7 = 0

x^{2} - 2 x + 2 + ∣ x - 2 ∣ = 2 ∣ x - 1 ∣

∣ 3 x - 2 ∣ = 14

∣ 5 y - 6 ∣ = ∣ 6 - 5 y ∣
