Schritte zur Lösung

∣ 7 x + 10 ∣ = 14

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

7 x + 10 = - 14 or 7 x + 10 = 14

7 x + 10 = - 14 or 7 x + 10 = 14

x = - \frac{24}{7} or x = \frac{4}{7}

∣ x - 1 ∣ + 8 = 2

- 3 1 - \frac{2}{3} v = - 9

3 = ∣ m + 2 ∣

∣ x - 9 ∣ = 3

∣ a ∣ - \frac{3}{4} = - \frac{5}{8}
