Schritte zur Lösung

∣ 9 x + 3 ∣ = 7

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

9 x + 3 = - 7 or 9 x + 3 = 7

9 x + 3 = - 7 or 9 x + 3 = 7

x = - \frac{10}{9} or x = \frac{4}{9}

- 12 = - 4 ∣ 3 + 8 x ∣

- 9 = ∣ - 8 r ∣ - 6

∣ x ∣^{2} = 4

7 + ∣ x + 3 ∣ = 1

∣ 6 x - 1 ∣ + 4 = 1
