Dezimale

n = - 1.8, n = 1.4

Schritte zur Lösung

∣ 5 n + 1 ∣ = 8

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

5 n + 1 = - 8 or 5 n + 1 = 8

5 n + 1 = - 8 or 5 n + 1 = 8

n = - \frac{9}{5} or n = \frac{7}{5}

∣ 4 x ∣ = 24

\frac{∣ n ∣}{3} + 5 = 8

∣ u ∣ - 13 = - 7

∣ x ∣ + 4 = 7

∣ x - 0.15 ∣ = 5
