∣ x - 4 ∣ = \frac{10}{7}

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

x - 4 = - \frac{10}{7} or x - 4 = \frac{10}{7}

x - 4 = - \frac{10}{7} or x - 4 = \frac{10}{7}

x = \frac{18}{7} or x = \frac{38}{7}

∣ x + 9 ∣ = 7

- 3 ∣ 2 w ∣ = - 6

x^{2} - 4 ∣ x ∣ + 4 = 0

∣ 9 - 5 x ∣ = 1

10 - 2 ∣ x - 1 ∣ = 1
