∣ - 9 + x ∣ = 1

x = 8 or x = 10

Schritte zur Lösung

∣ - 9 + x ∣ = 1

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

- 9 + x = - 1 or - 9 + x = 1

- 9 + x = - 1 or - 9 + x = 1

x = 8 or x = 10

3 ∣ 5 x - 4 ∣ + 21 = 25

X^{2} - 4 ∣ X - 1 ∣ + 5 X + 3 = 0

k^{2} - 5 k = 6

∣ v + 3 ∣ = 5

x^{2} + 7 x - 8 = ∣ x + 1 ∣
