Schritte zur Lösung

∣ 3.2 x - 1 ∣ = 4

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

3.2 x - 1 = - 4 or 3.2 x - 1 = 4

3.2 x - 1 = - 4 or 3.2 x - 1 = 4

x = - \frac{15}{16} or x = \frac{25}{16}

- 8 - 10 \times (- 7)

x - 2.9 \leq - 4.4

- X - 1 = - 5

f a c t or 8 - 125 x^{3}

7 x^{2} = 175
