∣ 4 x + 6 ∣ = 9

x = - \frac{15}{4} or x = \frac{3}{4}

Dezimale

x = - 3.75, x = 0.75

Schritte zur Lösung

∣ 4 x + 6 ∣ = 9

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

4 x + 6 = - 9 or 4 x + 6 = 9

4 x + 6 = - 9 or 4 x + 6 = 9

x = - \frac{15}{4} or x = \frac{3}{4}

∣ 6 x + 2 ∣ + 12 = 7

so l v e f or y, ∣ y ∣ = 2 - 5 x

\frac{2}{3} x - 4 = 8

∣ 4 x - 6 ∣ = 10

18 ∣ 4 x - 9 ∣ - 7 = 9 x
