∣ - 2 x ∣ = 8

x = - 4 or x = 4

Schritte zur Lösung

∣ - 2 x ∣ = 8

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

- 2 x = - 8 or - 2 x = 8

- 2 x = - 8 or - 2 x = 8

x = - 4 or x = 4

∣ 7 x - 6 ∣ \leq 29

f a c t or 2 - 5

f a c t or 3 x^{2} + 3

f a c t or 2 x^{2} - 20 x^{5}

\frac{5 x}{2} - \frac{2 x + 3}{6} = \frac{5}{3}
