|n+2|=4

Lösung

∣ n + 2 ∣ = 4

n = - 6 or n = 2

Schritte zur Lösung

∣ n + 2 ∣ = 4

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

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

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

n = - 6 or n = 2

∣ 5 x + 3 ∣ 8 - 6 x + 2 = 0

∣ 2 x - 4 ∣ - 6 = 17

1 = ∣ d - 6 ∣ - 3

4 ∣ 2 x - 3 ∣ = 8

∣ p + 6 ∣ + 6 = 32
