\frac{b}{6} = 1

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

\frac{b}{6} = - 1 or \frac{b}{6} = 1

\frac{b}{6} = - 1 or \frac{b}{6} = 1

b = - 6 or b = 6

∣ 2 a + 4 ∣ = ∣ 3 a - 2 ∣

so l v e f or x, \frac{x}{5} = 3

∣ x + 1 ∣ - 3 = - x

∣ 2 x ∣ + 8 = 24

4 - 6 ∣ 3 - 5 a ∣ = - 104
