Schritte zur Lösung

7 x - \frac{1}{7} = 1

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

7 x - \frac{1}{7} = - 1 or 7 x - \frac{1}{7} = 1

7 x - \frac{1}{7} = - 1 or 7 x - \frac{1}{7} = 1

x = - \frac{6}{49} or x = \frac{8}{49}

∣ x ∣ + 4 = 0

∣ 3 u + 9 ∣ = 3

4 = \frac{3}{4} ∣ 2 x - 3 ∣ + 1

∣ - 2 x ∣ = ∣ 8 ∣

∣ 8 n + 10 ∣ = 22
