Schritte zur Lösung

∣ 4 x - 4 ∣ = 7

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

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

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

x = - \frac{3}{4} or x = \frac{11}{4}

- 6 ∣ 5 + 10 x ∣ = - 90

∣ - 4 x - 1 ∣ - 1 = 6

5 = ∣ w + 3 ∣

9 = ∣ w - 7 ∣

∣ w - 4 ∣ = 24
