x = - 4 or x = \frac{20}{3}

Dezimale

x = - 4, x = 6.66666 \dots

Schritte zur Lösung

∣ - 3 x + 4 ∣ = 16

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

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

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

x = - 4 or x = \frac{20}{3}

∣ c - 3 ∣ = 1

so l v e f or x, ∣ 3 - 6 x ∣ = 39

\frac{1}{2} ∣ x ∣ - 2 = 3

4 = \frac{c}{4}

∣ x - 1 ∣ + 17 = 23
