|v+4|=9

Lösung

∣ v + 4 ∣ = 9

v = - 13 or v = 5

Schritte zur Lösung

∣ v + 4 ∣ = 9

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

v + 4 = - 9 or v + 4 = 9

v + 4 = - 9 or v + 4 = 9

v = - 13 or v = 5

∣ w ∣ - 8 = - 1

∣ d ∣ + 5 = 6

∣ x + 3 ∣ + 2 = 5

5 ∣ 3 + 4 k ∣ = - 115

x^{2} - 2 = 1
