∣ 2 x ∣ = 1.5

x = - 0.75 or x = 0.75

Schritte zur Lösung

∣ 2 x ∣ = 1.5

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

2 x = - 1.5 or 2 x = 1.5

2 x = - 1.5 or 2 x = 1.5

x = - 0.75 or x = 0.75

3 = - 2 ∣ 41 s - 5 ∣ + 3

x^{2} + x - 28 = 28

∣ x + 5 ∣ = - 9

∣ x + 5 ∣ = - 4

∣ x + 5 ∣ = - 6
