Schritte zur Lösung

∣ 2 w - 3 ∣ = 5

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

2 w - 3 = - 5 or 2 w - 3 = 5

2 w - 3 = - 5 or 2 w - 3 = 5

w = - 1 or w = 4

x^{2} - 5 x + 4 = 4

∣ k - 2 ∣ = - 8

3 - ∣ 2 x - 2 ∣ = ∣ 5 - 2 x ∣

- 6 ∣ 3 y ∣ + 23 = - 1

∣ 3 x - 2 ∣ = 2 x - 3
