Schritte zur Lösung

∣ 10 + 9 k ∣ = 35

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

10 + 9 k = - 35 or 10 + 9 k = 35

10 + 9 k = - 35 or 10 + 9 k = 35

k = - 5 or k = \frac{25}{9}

9 ∣ 7 z + 5 ∣ = 27

∣ 18 x - 5 ∣ = 0

92 = ∣ r - 900 ∣ - 8

2 - 9 ∣ - 5 x - 10 ∣ = - 88

∣ 5 x + 10 ∣ = 5
