d = - \frac{10}{3} or d = 6

Dezimale

d = - 3.33333 \dots, d = 6

Schritte zur Lösung

∣ 3 d - 4 ∣ = 14

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

3 d - 4 = - 14 or 3 d - 4 = 14

3 d - 4 = - 14 or 3 d - 4 = 14

d = - \frac{10}{3} or d = 6

∣ - 4 + 5 x ∣ = 2

∣ x - 3 ∣ + 18 = 6

a = ∣ 5 x - 3 ∣ - 4

∣ x + 4 ∣ = - 2

∣ x + 4 ∣ = - 4
