Schritte zur Lösung

∣ 7 x - 8 ∣ = 48

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

7 x - 8 = - 48 or 7 x - 8 = 48

7 x - 8 = - 48 or 7 x - 8 = 48

x = - \frac{40}{7} or x = 8

∣ 5 - 2 u ∣ = 7

5 - 3 ∣ 5 x + 11 ∣ = - 19

4 ∣ 4 - 2 n ∣ - 3 = 93

∣ u - 8 ∣ = - \frac{1}{3}

∣ 3 x + 1 ∣ - 3 = 7
