Schritte zur Lösung

∣ 10 x - 8 ∣ = 38

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

10 x - 8 = - 38 or 10 x - 8 = 38

10 x - 8 = - 38 or 10 x - 8 = 38

x = - 3 or x = \frac{23}{5}

\frac{3 x - 9}{2} = 3

∣ 9 b - 6 ∣ - 4 = - 73

∣ 2 x - 7 ∣ = 0

∣ x + 2 ∣ = 4 - 3 x

∣ 6 - 2 x ∣ = - 3
