|x-1.5|=2

Lösung

∣ x - 1.5 ∣ = 2

x = - 0.5 or x = 3.5

Schritte zur Lösung

∣ x - 1.5 ∣ = 2

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

x - 1.5 = - 2 or x - 1.5 = 2

x - 1.5 = - 2 or x - 1.5 = 2

x = - 0.5 or x = 3.5

∣ x - 2 ∣ = ∣ 2 x + 1 ∣

∣ 2 x - 1 ∣ - 9 = 0

∣ 20 + 2 x ∣ = ∣ 4 x + 4 ∣

∣ x + 3 ∣ + ∣ x - 2 ∣ = 5

x^{2} + x + 1 + ∣ 2 x - 3 ∣ = 4 x
