∣ 2 x - 4 ∣ + \geq = 2

x = 1 or x = 3

Schritte zur Lösung

∣ 2 x - 4 ∣ = 2

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

2 x - 4 = - 2 or 2 x - 4 = 2

2 x - 4 = - 2 or 2 x - 4 = 2

x = 1 or x = 3

∣ 5 x - 3 ∣ = \frac{2}{3}

3 ∣ 6 c + 2 ∣ + 2 = 11

∣ 2 x - 7 ∣ + 1 = x

3 ∣ x + 1 ∣ + 9 = 6

∣ d - 75 ∣ = 20
