Schritte zur Lösung

∣ 8 + 10 k ∣ = 38

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

8 + 10 k = - 38 or 8 + 10 k = 38

8 + 10 k = - 38 or 8 + 10 k = 38

k = - \frac{23}{5} or k = 3

\frac{2}{7} ∣ - x - 3 ∣ - 10 = - 8

∣ 3 k - 2 ∣ = 2 ∣ k + 2 ∣

4 ∣ x - 8 ∣ = 36

- ∣ 14 n + 2 ∣ = - 7

2 ∣ 4 x + 2 ∣ = 52
