|-18+x|=2

Lösung

∣ - 18 + x ∣ = 2

x = 16 or x = 20

Schritte zur Lösung

∣ - 18 + x ∣ = 2

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

- 18 + x = - 2 or - 18 + x = 2

- 18 + x = - 2 or - 18 + x = 2

x = 16 or x = 20

- 3 ∣ 4 x - 3 ∣ + 20 = 5

x^{2} - 3 x = 6 - 4 x

2 x = ∣ x - 1 ∣

5 = ∣ p - 4 ∣

∣ x - 1 ∣ - 1 = 0
