Lösung

∣ 9 - 2 x ∣ = 1

x = 4 or x = 5

Schritte zur Lösung

∣ 9 - 2 x ∣ = 1

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

9 - 2 x = - 1 or 9 - 2 x = 1

9 - 2 x = - 1 or 9 - 2 x = 1

x = 4 or x = 5

∣ 3 x - 5 ∣ - 9 = 2

\frac{1}{4} x - 5 = 8

b^{2} = b^{2}

2 ∣ d ∣ + 3 = 5

x^{2} - 2 x = 12
