Schritte zur Lösung

∣ 3 + 10 x ∣ = 23

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

3 + 10 x = - 23 or 3 + 10 x = 23

3 + 10 x = - 23 or 3 + 10 x = 23

x = - \frac{13}{5} or x = 2

∣ x + 2 ∣ + 2 = 5 x

x^{2} - 9 = - 2 x + 6

- ∣ 2 x + 1 ∣ + 1 = 1

- ∣ 4 - 8 x ∣ = 12

2 = m + \frac{2}{3}
