Schritte zur Lösung

∣ 7 - 3 x ∣ = 3

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

7 - 3 x = - 3 or 7 - 3 x = 3

7 - 3 x = - 3 or 7 - 3 x = 3

x = \frac{4}{3} or x = \frac{10}{3}

6 x + 4 = 9 x - 5

x^{2} + 8 = 4

x^{2} - 5 x + 4 \geq 0

s im pl i f y \frac{a b}{3 ab}

18 x^{2} + 4 x + 12 = 6 x^{2}
