Schritte zur Lösung

∣ 2 - 9 p ∣ = 25

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

2 - 9 p = - 25 or 2 - 9 p = 25

2 - 9 p = - 25 or 2 - 9 p = 25

p = - \frac{23}{9} or p = 3

∣ y + 7 ∣ = 2 y + 5

∣ 1 - 3 t ∣ + 2 = 15

∣ - 3 + k ∣ = 1

∣ x - 1 ∣ + 5 = - 2

∣ 4 r + 7 ∣ = 43
