Schritte zur Lösung

∣ 15 - 9 x ∣ = 48

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

15 - 9 x = - 48 or 15 - 9 x = 48

15 - 9 x = - 48 or 15 - 9 x = 48

x = - \frac{11}{3} or x = 7

∣ x - 5 ∣ = - 7

5 + ∣ 4 x + 8 ∣ = 25

∣ x ∣ = x^{2} + x - 35

∣ 3 + 2 x ∣ = 17

∣ m - 3 ∣ - 2 = 0
