Schritte zur Lösung

∣ 5 x - 3 ∣ = 20

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

5 x - 3 = - 20 or 5 x - 3 = 20

5 x - 3 = - 20 or 5 x - 3 = 20

x = - \frac{17}{5} or x = \frac{23}{5}

∣ 5 x - 3 ∣ = - 6

3 - \frac{x}{2} = \frac{x}{3} + 6

∣ 7 x - 7 ∣ = ∣ x - 1 ∣

∣ 5 - x ∣ = 0

∣ 2 - 2 x ∣ = 14
