Lösung

∣ 100 - 5 x ∣ = 50

x = 10 or x = 30

Schritte zur Lösung

∣ 100 - 5 x ∣ = 50

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

100 - 5 x = - 50 or 100 - 5 x = 50

100 - 5 x = - 50 or 100 - 5 x = 50

x = 10 or x = 30

1 - 7 ∣ 7 m + 10 ∣ = 29

2 ∣ x - 9 ∣ - 4 = 20

∣ a x ∣ + b = c

3 ∣ x - 4 ∣ = 10

∣ q ∣ + 1 = - 58
