Schritte zur Lösung

∣ 7 x - 1 ∣ = 10

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

7 x - 1 = - 10 or 7 x - 1 = 10

7 x - 1 = - 10 or 7 x - 1 = 10

x = - \frac{9}{7} or x = \frac{11}{7}

f a c t or x^{2} + 4 x + 8

∣ 2 x - 7 ∣ \geq 1

5 x + 2 \leq - 18

s im pl i f y (- 32)^{\frac{1}{5}}

3 - 2 x = 5 - 4 x
