Lösung

∣ x - 640 ∣ = 90

x = 550 or x = 730

Schritte zur Lösung

∣ x - 640 ∣ = 90

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

x - 640 = - 90 or x - 640 = 90

x - 640 = - 90 or x - 640 = 90

x = 550 or x = 730

9 - 2 \cdot ∣ - 8 + n ∣ = - 3

ln ∣ x (20 - x) ∣ = 70 t + c

∣ 6 x + 10 ∣ = - 8

∣ x - 13 ∣ = 10

2 x^{2} - 3 = 5 x
