Lösung

∣ 4 n + 2 ∣ = 34

n = - 9 or n = 8

Schritte zur Lösung

∣ 4 n + 2 ∣ = 34

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

4 n + 2 = - 34 or 4 n + 2 = 34

4 n + 2 = - 34 or 4 n + 2 = 34

n = - 9 or n = 8

∣ y ∣ = - 8

∣ x - 2 ∣ = 5 x + 14

∣ 5 y - 2 ∣ = 0

∣ x - 1 ∣ = - 6

7 ∣ x - 6 ∣ = 8
