d = - 12 or d = 8

Schritte zur Lösung

∣ d + 2 ∣ = 10

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

d + 2 = - 10 or d + 2 = 10

d + 2 = - 10 or d + 2 = 10

d = - 12 or d = 8

∣ x - 1 ∣ + ∣ 2 x - 3 ∣ = 2

5 = 5 ∣ f + 7 ∣

∣ c ∣ = - 5

3 ∣ 4 x + 4 ∣ - 8 = - 2

∣ x - 5 ∣ = ∣ 7 - x ∣
