∣ x - 2.5 ∣ = 6

x = - 3.5 or x = 8.5

Schritte zur Lösung

∣ x - 2.5 ∣ = 6

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

x - 2.5 = - 6 or x - 2.5 = 6

x - 2.5 = - 6 or x - 2.5 = 6

x = - 3.5 or x = 8.5

∣ x - 1 ∣ = ∣ 2 x + 1 ∣ - 1

∣ 3 - 7 x ∣ = 19

2 ∣ 5 x ∣ = 50

∣ x + 3 ∣ = 3 + 2 x

∣ x - 7 ∣ = ∣ 3 x - 1 ∣
