∣ 2 z - 3 ∣ = 2

z = \frac{1}{2} or z = \frac{5}{2}

Dezimale

z = 0.5, z = 2.5

Schritte zur Lösung

∣ 2 z - 3 ∣ = 2

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

2 z - 3 = - 2 or 2 z - 3 = 2

2 z - 3 = - 2 or 2 z - 3 = 2

z = \frac{1}{2} or z = \frac{5}{2}

2 ∣ 2 x - 5 ∣ - 5 = 9

∣ x ∣ = - 18.9

∣ x ∣ = - 18.3

5 + 6 ∣ 2 - 2 x ∣ - 1 = 28

∣ - 4 n ∣ = 4
