Lösung

∣ x + 4 ∣ = 5

x = - 9 or x = 1

Schritte zur Lösung

∣ x + 4 ∣ = 5

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

x + 4 = - 5 or x + 4 = 5

x + 4 = - 5 or x + 4 = 5

x = - 9 or x = 1

\frac{k}{4} \geq 1 or \frac{k}{3} \leq - 1

3 s + 4 \geq 10

- 5 x + 2 - x + 1 = 0

s im pl i f y 1 + \frac{2}{3 + \frac{5}{1 - \frac{1}{3}}}

\frac{p}{2} \leq 2
