|4x+3|=16

Lösung

∣ 4 x + 3 ∣ = 16

x = - \frac{19}{4} or x = \frac{13}{4}

Dezimale

x = - 4.75, x = 3.25

Schritte zur Lösung

∣ 4 x + 3 ∣ = 16

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

4 x + 3 = - 16 or 4 x + 3 = 16

4 x + 3 = - 16 or 4 x + 3 = 16

x = - \frac{19}{4} or x = \frac{13}{4}

\frac{x}{2} + \frac{1}{3} = 4

x^{2} - 4 + 9 = 5

∣ x + 4 ∣ = 29

∣ x + 1 ∣ + ∣ x - 1 ∣ = x + 4

so l v e f or y, x = - 2 ∣ y ∣ - 5
