Schritte zur Lösung

∣ 5 - 3 x ∣ = 7

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

5 - 3 x = - 7 or 5 - 3 x = 7

5 - 3 x = - 7 or 5 - 3 x = 7

x = - \frac{2}{3} or x = 4

9 - 8 ∣ r - 5 ∣ = 25

2 ∣ x + 5 ∣ = 16

5 - 2 (x^{3}) = 0

∣ 3 + x ∣ = - \frac{1}{2}

\frac{∣ - 7 x + 2 ∣}{5} = 4
