Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

- \frac{1}{5} x - 4 = - 6 or - \frac{1}{5} x - 4 = 6

- \frac{1}{5} x - 4 = - 6 or - \frac{1}{5} x - 4 = 6

x = - 50 or x = 10

∣ n ∣ + 3 = 2

∣ 2 x + 7 ∣ + 5 = 8

3 = - 2 \frac{1}{4} x - 5 + 3

3 ∣ 8 - 4 B ∣ = 66

7 = - 5 ∣ x + 1 ∣ - 3
