∣ 4 x + 3 ∣ = 5

x = - 2 or x = \frac{1}{2}

Dezimale

x = - 2, x = 0.5

Schritte zur Lösung

∣ 4 x + 3 ∣ = 5

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

4 x + 3 = - 5 or 4 x + 3 = 5

4 x + 3 = - 5 or 4 x + 3 = 5

x = - 2 or x = \frac{1}{2}

∣ 4 a - 8 ∣ = 8

∣ - 2 x - 12 ∣ = 10

2 = ∣ m + 23 ∣

- 7 ∣ - 8 x - 6 ∣ = - 70

f (- 2) = ∣ x + 3 ∣, x \leq - 1
