Schritte zur Lösung

\frac{1 - x}{3} = 9

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

\frac{1 - x}{3} = - 9 or \frac{1 - x}{3} = 9

\frac{1 - x}{3} = - 9 or \frac{1 - x}{3} = 9

x = - 26 or x = 28

\frac{1 - x}{3} = 5

4 2 x^{7} = 16

4 ∣ 3 y - 3 ∣ = 0

∣ 3 x - 5 ∣ = 2 x + 1

3 ∣ y + 3 ∣ - 12 = 0
