Schritte zur Lösung

∣ - 3 a + 8 ∣ = 11

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

- 3 a + 8 = - 11 or - 3 a + 8 = 11

- 3 a + 8 = - 11 or - 3 a + 8 = 11

a = - 1 or a = \frac{19}{3}

4 - 4 ∣ 6 - 3 x ∣ = - 16

4 - 5 ∣ 10 + 5 x ∣ = - 51

∣ 3 x - 6 ∣ = 12

∣ 8 w + 5 ∣ = 21

25 - x^{2} = x^{2} - 25
