|b-11|=15

Lösung

∣ b - 11 ∣ = 15

b = - 4 or b = 26

Schritte zur Lösung

∣ b - 11 ∣ = 15

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

b - 11 = - 15 or b - 11 = 15

b - 11 = - 15 or b - 11 = 15

b = - 4 or b = 26

5 ∣ p ∣ = - 9

x^{4} = ∣ x ∣

5 ∣ x + 8 ∣ = 10

∣ x + 7 ∣ = x + 6

0 = - 2 ∣ r + 100 ∣
