Schritte zur Lösung

x + \frac{2}{2} = 2

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

x + \frac{2}{2} = - 2 or x + \frac{2}{2} = 2

x + \frac{2}{2} = - 2 or x + \frac{2}{2} = 2

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

4 + ∣ 3 x - 10 ∣ = 15

∣ x - 7 ∣ = 45

x^{2} - 17 ∣ x ∣ + 72 = 0

∣ 5 x - 7 ∣ - 12 = - 3

- 1 = - 4 ∣ x - 3 ∣
