|3(x-4)|=9

Lösung

∣ 3 (x - 4) ∣ = 9

x = 1 or x = 7

Schritte zur Lösung

∣ 3 (x - 4) ∣ = 9

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

3 (x - 4) = - 9 or 3 (x - 4) = 9

3 (x - 4) = - 9 or 3 (x - 4) = 9

x = 1 or x = 7

∣ 2 (x - 2) ∣ = \frac{5}{2}

x^{2} - x + 1 + ∣ 2 x - 3 ∣ = 4 x

(- x^{2} + x - 1) 3 + x^{2} - x + 1 = 0

(x + 3) ∣ x + 2 ∣ + ∣ 2 x + 3 ∣ + 1 = 0

∣ x - 2 ∣ + ∣ x - 4 ∣ = 5
