w = - 5 or w = - 1

Schritte zur Lösung

∣ 3 w + 9 ∣ = 6

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

3 w + 9 = - 6 or 3 w + 9 = 6

3 w + 9 = - 6 or 3 w + 9 = 6

w = - 5 or w = - 1

∣ 4 p - 8 ∣ = 36

∣ x + 5 ∣ = x + 5

∣ 6 x ∣ = x^{2} + 6 x - 13

8 = ∣ f + 2 ∣ + 1

5 u^{4} - 7 + 3 = 8
