|2x-11|=3

Lösung

∣ 2 x - 11 ∣ = 3

x = 4 or x = 7

Schritte zur Lösung

∣ 2 x - 11 ∣ = 3

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

2 x - 11 = - 3 or 2 x - 11 = 3

2 x - 11 = - 3 or 2 x - 11 = 3

x = 4 or x = 7

∣ 2 x - 11 ∣ = 5

∣ x - 5 ∣ = x + 3

∣ 2 x - 4 ∣ + 5 = 8

e - 2 ∣ 3 k - 11 ∣ + 8 = - 54

∣ 7 x + 5 ∣ = 9
