x = - \frac{11}{2} or x = \frac{13}{2}

Dezimale

x = - 5.5, x = 6.5

Schritte zur Lösung

∣ 2 x - 1 ∣ = 12

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

2 x - 1 = - 12 or 2 x - 1 = 12

2 x - 1 = - 12 or 2 x - 1 = 12

x = - \frac{11}{2} or x = \frac{13}{2}

∣ 3 x + 3 ∣ = 11

∣ 3 x + 3 ∣ = 12

- 8 = - 4 ∣ k - 5 ∣

∣ 3 x + 3 ∣ = 24

2 ∣ x ∣ + 1 = 5
