Schritte zur Lösung

∣ 120 x - 40 ∣ = 60

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

120 x - 40 = - 60 or 120 x - 40 = 60

120 x - 40 = - 60 or 120 x - 40 = 60

x = - \frac{1}{6} or x = \frac{5}{6}

- 5 (x - 3) - 3 x - 2 = 45

5 x^{2} + 80 = 0

s im pl i f y - (\frac{1}{2})^{2}

3 x + 2 \leq 2 x - 4

2 x + 5 = - 3 x + 8 + 5 x
