∣ x - 6 ∣ = \frac{4}{7}

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

x - 6 = - \frac{4}{7} or x - 6 = \frac{4}{7}

x - 6 = - \frac{4}{7} or x - 6 = \frac{4}{7}

x = \frac{38}{7} or x = \frac{46}{7}

2 = ln y - x^{2}

2 x + 1 = 5 ∣ 4 - 2 x ∣ - 10

- 3 ∣ x + 4 ∣ = - 21

7 ∣ x ∣ - 9 = 26

∣ x - 3 ∣ - 8 = 0
