Lösung

∣ 2 p + 13 ∣ = 31

p = - 22 or p = 9

Schritte zur Lösung

∣ 2 p + 13 ∣ = 31

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

2 p + 13 = - 31 or 2 p + 13 = 31

2 p + 13 = - 31 or 2 p + 13 = 31

p = - 22 or p = 9

1.5 y + 3.4 = 7.9

\frac{x + 2}{x - 3} < 0

s im pl i f y (4 - 3 i)^{2}

(2 x - 3)^{2} = 49

x + 6 = 14
