|3p+9|=39

Lösung

∣ 3 p + 9 ∣ = 39

p = - 16 or p = 10

Schritte zur Lösung

∣ 3 p + 9 ∣ = 39

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

3 p + 9 = - 39 or 3 p + 9 = 39

3 p + 9 = - 39 or 3 p + 9 = 39

p = - 16 or p = 10

∣ 7 x + 2 ∣ = 4 x + 11

∣ 4 x - 1 ∣ - 6 = 2 x + 2

∣ - 2 f ∣ - 2 = 8

2 x + ∣ 3 x - 2 ∣ = x + 2

x^{2} - 2 x - 5 = 2
