|x+8|=3.5

Lösung

∣ x + 8 ∣ = 3.5

x = - 11.5 or x = - 4.5

Schritte zur Lösung

∣ x + 8 ∣ = 3.5

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

x + 8 = - 3.5 or x + 8 = 3.5

x + 8 = - 3.5 or x + 8 = 3.5

x = - 11.5 or x = - 4.5

3 ∣ 3 - x ∣ - 4 ∣ 2 x + 1 ∣ = 2

∣ x ∣ + ∣ x + 1 ∣ + ∣ x + 2 ∣ = 3

∣ x - 2 ∣ + ∣ x ∣ = x^{2} - 2 x

x + 2 = 3

∣ x - 1 ∣ + ∣ x - 2 ∣ = 5
