|x-9|=3

Lösung

∣ x - 9 ∣ = 3

x = 6 or x = 12

Schritte zur Lösung

∣ x - 9 ∣ = 3

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

x - 9 = - 3 or x - 9 = 3

x - 9 = - 3 or x - 9 = 3

x = 6 or x = 12

∣ a ∣ - \frac{3}{4} = - \frac{5}{8}

∣ 3 x - 1 ∣ = ∣ 2 x + 6 ∣

∣ x - 3 ∣ = ∣ x + 1 ∣

∣ 3 - 2 (3 x - 2) ∣ = ∣ 4 x - 1 ∣

∣ 6 x - 2 ∣ - 3 = - 3
