∣ x + 6 ∣ = 15

x = - 21 or x = 9

Schritte zur Lösung

∣ x + 6 ∣ = 15

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

x + 6 = - 15 or x + 6 = 15

x + 6 = - 15 or x + 6 = 15

x = - 21 or x = 9

7 - ∣ 4 x - 3 ∣ = - 5

∣ 4 - 5 x ∣ = 7

∣ x ∣ + x^{2} - 1 - x^{2} = 0

∣ v ∣ + 13 = 20

4 + \frac{b}{6} = 5
