|-b+6|=99

Lösung

∣ - b + 6 ∣ = 99

b = - 93 or b = 105

Schritte zur Lösung

∣ - b + 6 ∣ = 99

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

- b + 6 = - 99 or - b + 6 = 99

- b + 6 = - 99 or - b + 6 = 99

b = - 93 or b = 105

∣ x + 5 ∣ = x - 4

4 ∣ 5 g - 12 ∣ = - 12

- 5 ∣ x - 4 ∣ = - 10

\frac{1}{3} x - 2 = 6

- 4 ∣ x ∣ = - 16
