|x-4|=12

Lösung

∣ x - 4 ∣ = 12

x = - 8 or x = 16

Schritte zur Lösung

∣ x - 4 ∣ = 12

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

x - 4 = - 12 or x - 4 = 12

x - 4 = - 12 or x - 4 = 12

x = - 8 or x = 16

4 ∣ m + 3 ∣ - 3 = - 3

∣ x ∣ = x^{2} - 30

∣ 2 + 2 x ∣ + 1 = 3

∣ - 6 k ∣ = 30

12 = \frac{b}{6}
