∣ p - 9 ∣ = 18

p = - 9 or p = 27

Schritte zur Lösung

∣ p - 9 ∣ = 18

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

p - 9 = - 18 or p - 9 = 18

p - 9 = - 18 or p - 9 = 18

p = - 9 or p = 27

∣ 3 x - 12 ∣ = 9

x + 15 = ∣ 4 x - 45 ∣

4 ∣ x + 8 ∣ = 56

∣ 8 x + 9 ∣ + 6 = 12

- 9 ∣ 7 + 9 b ∣ = 99
