|x-9|=1

Lösung

∣ x - 9 ∣ = 1

x = 8 or x = 10

Schritte zur Lösung

∣ x - 9 ∣ = 1

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

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

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

x = 8 or x = 10

∣ g - 2 ∣ = 7

4 - \frac{1}{2} x = - 9

∣ - x - 1 ∣ = 0

- 2 ∣ 4 w ∣ = - 32

∣ 5 - 7 x ∣ + 10 = 43
