∣ 12 - 2 x ∣ = 7

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

12 - 2 x = - 7 or 12 - 2 x = 7

12 - 2 x = - 7 or 12 - 2 x = 7

x = \frac{5}{2} or x = \frac{19}{2}

∣ x - 3 ∣ + 4 x = 1 + x

∣ 2 + x ∣ = 1

\frac{∣ 6 x + 9 ∣}{3} = 5

3 ∣ 2 x + 5 ∣ + 11 = 8

∣ 3 x - 2 ∣ + 3 = 3
