|d-100|=50

Lösung

∣ d - 100 ∣ = 50

d = 50 or d = 150

Schritte zur Lösung

∣ d - 100 ∣ = 50

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

d - 100 = - 50 or d - 100 = 50

d - 100 = - 50 or d - 100 = 50

d = 50 or d = 150

∣ 6 x ∣ = 7

3 - ∣ 4 x - 5 ∣ = - 15

∣ 5 - 4 x ∣ - 3 = 4

- 3 ∣ r - 4 ∣ - 7 = - 22

7 ∣ 2 - 11 x ∣ = 21
