|b-4|=1

Lösung

∣ b - 4 ∣ = 1

b = 3 or b = 5

Schritte zur Lösung

∣ b - 4 ∣ = 1

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

b - 4 = - 1 or b - 4 = 1

b - 4 = - 1 or b - 4 = 1

b = 3 or b = 5

c ∣ 3 x + 4 ∣ + 2 = - 5

∣ 5 + 7 x ∣ = 13

∣ y ∣ - 4 = 13

∣ 3 u - 54 ∣ = 12

∣ z + 2 ∣ = - 8
