|5x+2|=18

Lösung

∣ 5 x + 2 ∣ = 18

x = - 4 or x = \frac{16}{5}

Dezimale

x = - 4, x = 3.2

Schritte zur Lösung

∣ 5 x + 2 ∣ = 18

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

5 x + 2 = - 18 or 5 x + 2 = 18

5 x + 2 = - 18 or 5 x + 2 = 18

x = - 4 or x = \frac{16}{5}

∣ 4 x - 8 ∣ + ∣ 2 - x ∣ = 5

\frac{x}{5} + \frac{1}{3} = 2

∣ x - 4 ∣ = 3 x

∣ x + 9 ∣ + 4 = 11

so l v e f or y, y^{2} = ∣ x ∣
