Schritte zur Lösung

∣ x + 5 ∣ = 1 0^{- 2}

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

x + 5 = - 1 0^{- 2} or x + 5 = 1 0^{- 2}

x + 5 = - 1 0^{- 2} or x + 5 = 1 0^{- 2}

x = - \frac{501}{100} or x = - \frac{499}{100}

3 \cdot ∣ x ∣ = x^{2} + 2 - 2

∣ 3 w - 18 ∣ = 0

∣ 6 x - 3 ∣ = 63

x ∣ x ∣ - 1 = 0

∣ 6 x - 3 ∣ = 21
