x = - 19 or x = 9

Schritte zur Lösung

∣ x + 5 ∣ = 14

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

x + 5 = - 14 or x + 5 = 14

x + 5 = - 14 or x + 5 = 14

x = - 19 or x = 9

s im pl i f y (\frac{4}{x})^{2}

2 x + 1 > 5

(x + 4) (3 x - 2) + 2 x - 1 = 3 x^{2} + x - 6

- 8 \leq 10 - x \leq 4

y (y - 4) = 1
