∣ 4 b + 10 ∣ = 12

b = - \frac{11}{2} or b = \frac{1}{2}

Dezimale

b = - 5.5, b = 0.5

Schritte zur Lösung

∣ 4 b + 10 ∣ = 12

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

4 b + 10 = - 12 or 4 b + 10 = 12

4 b + 10 = - 12 or 4 b + 10 = 12

b = - \frac{11}{2} or b = \frac{1}{2}

- ∣ x + 4 ∣ + 8 = 4

x^{2} + 6 x = 3 x + 18

8 - 2 ∣ 5 x - 10 ∣ = 15

2 - 10 ∣ k + 1 ∣ = - 78

- 4 ∣ 3 + x ∣ - 7 = - 15
