|1-2x|=3

Lösung

∣ 1 - 2 x ∣ = 3

x = - 1 or x = 2

Schritte zur Lösung

∣ 1 - 2 x ∣ = 3

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

1 - 2 x = - 3 or 1 - 2 x = 3

1 - 2 x = - 3 or 1 - 2 x = 3

x = - 1 or x = 2

4 ∣ 7 y + 2 ∣ - 11 = - 7

3 x^{2} - 7 ∣ x ∣ + 4 = 0

so l v e f or x, ∣ x ∣ + y = 2

- 1 - 2 ∣ 5 - 3 x ∣ = x

∣ 3 u + 6 ∣ = 42
