Schritte zur Lösung

∣ 1 - 3 x ∣ = 37

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

1 - 3 x = - 37 or 1 - 3 x = 37

1 - 3 x = - 37 or 1 - 3 x = 37

x = - 12 or x = \frac{38}{3}

∣ 3 x - 9 ∣ - ∣ 4 x - 6 ∣ = 4

∣ x - 2 ∣ + ∣ x ∣ = 2

∣ x - 1 ∣ = 2 x + 3

∣ x - 1 ∣ - 2 ∣ 2 - x ∣ = 0

14 ∣ x - 2 ∣ + 1 = 29
