w = 1 or w = 7

Schritte zur Lösung

∣ 3 w - 12 ∣ = 9

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

3 w - 12 = - 9 or 3 w - 12 = 9

3 w - 12 = - 9 or 3 w - 12 = 9

w = 1 or w = 7

- 2 ∣ - b ∣ = - 14

x^{2} - 2 x - x = 0

∣ x ∣ = - x - 1

\frac{∣ 2 x - 10 ∣}{6} = 2

∣ d - 7 ∣ - 8 = 80
