Schritte zur Lösung

∣ - 10 n - 7 ∣ = 17

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

- 10 n - 7 = - 17 or - 10 n - 7 = 17

- 10 n - 7 = - 17 or - 10 n - 7 = 17

n = - \frac{12}{5} or n = 1

\frac{x}{7} = 5

∣ 3 - 2 r ∣ + 10 = 7

2 ∣ x - 4 ∣ - 3 = - 2

x^{2} - ∣ x ∣ - 6 = 0

4 ∣ 7 x + 2 ∣ - 8 = - 7
