|4x+4|=17

Lösung

∣ 4 x + 4 ∣ = 17

x = - \frac{21}{4} or x = \frac{13}{4}

Dezimale

x = - 5.25, x = 3.25

Schritte zur Lösung

∣ 4 x + 4 ∣ = 17

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

4 x + 4 = - 17 or 4 x + 4 = 17

4 x + 4 = - 17 or 4 x + 4 = 17

x = - \frac{21}{4} or x = \frac{13}{4}

so l v e f or x, f = ∣ x ∣

∣ 4 x + 4 ∣ = 24

∣ 3 x + 5 ∣ = 2

∣ 3 x + 5 ∣ = 6

∣ 2 x + 1 ∣ + 15 = 8
