Lösung

löse nach

x, ∣ 3 - 6 x ∣ = 39

x = - 6 or x = 7

Schritte zur Lösung

∣ 3 - 6 x ∣ = 39

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

3 - 6 x = - 39 or 3 - 6 x = 39

3 - 6 x = - 39 or 3 - 6 x = 39

x = - 6 or x = 7

\frac{1}{2} ∣ x ∣ - 2 = 3

4 = \frac{c}{4}

∣ x - 1 ∣ + 17 = 23

\frac{x ^{2}}{4} = 1

∣ x + 9 ∣ + ∣ x - 3 ∣ + ∣ x + 7 ∣ + ∣ x - 4 ∣ = 8
