|3x-(4x-2)|=4

Lösung

∣ 3 x - (4 x - 2) ∣ = 4

x = - 2 or x = 6

Schritte zur Lösung

∣ 3 x - (4 x - 2) ∣ = 4

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

3 x - (4 x - 2) = - 4 or 3 x - (4 x - 2) = 4

3 x - (4 x - 2) = - 4 or 3 x - (4 x - 2) = 4

x = - 2 or x = 6

48 = 40 + k \cdot 4

x^{2} - 3 x + 2 = - 1

11 (k - 1) = 7 (k - 9)

0 \leq 1
