Schritte zur Lösung

∣ 6 x + 7 ∣ = 9

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

6 x + 7 = - 9 or 6 x + 7 = 9

6 x + 7 = - 9 or 6 x + 7 = 9

x = - \frac{8}{3} or x = \frac{1}{3}

∣ 6 x + 7 ∣ = 4

2 x^{2} - 1 = x

x^{6} ∣ - 8 + 5 x ∣ - 4 = - 38

∣ y + 1 ∣ - 5 = 8

∣ - 3 z - 4 ∣ = 17
