|3v+9|=3

Lösung

∣ 3 v + 9 ∣ = 3

v = - 4 or v = - 2

Schritte zur Lösung

∣ 3 v + 9 ∣ = 3

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

3 v + 9 = - 3 or 3 v + 9 = 3

3 v + 9 = - 3 or 3 v + 9 = 3

v = - 4 or v = - 2

2 x + 9 x - 2 = 3 x - 5 - 4

3 c + 5 = 23

f a c t or 625 x^{4} - 16

7 x - 1 < 29 - 2 x

- 5 x^{2} + 7 x = - 9
