|v-4|=4

Lösung

∣ v - 4 ∣ = 4

v = 0 or v = 8

Schritte zur Lösung

∣ v - 4 ∣ = 4

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

v - 4 = - 4 or v - 4 = 4

v - 4 = - 4 or v - 4 = 4

v = 0 or v = 8

∣ 7 f - 2 ∣ = - 9

∣ z + 840 ∣ + 7 = 12

∣ - 4 b - 5 ∣ = 19

a ∣ b x + 5 ∣ - c = d

∣ x + 4 ∣ = 3 x - 12
