|4-5x|=7

Lösung

∣ 4 - 5 x ∣ = 7

x = - \frac{3}{5} or x = \frac{11}{5}

Dezimale

x = - 0.6, x = 2.2

Schritte zur Lösung

∣ 4 - 5 x ∣ = 7

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

4 - 5 x = - 7 or 4 - 5 x = 7

4 - 5 x = - 7 or 4 - 5 x = 7

x = - \frac{3}{5} or x = \frac{11}{5}

∣ x ∣ + x^{2} - 1 - x^{2} = 0

∣ v ∣ + 13 = 20

4 + \frac{b}{6} = 5

∣ 2 a + 4 ∣ = ∣ 3 a - 2 ∣

so l v e f or x, \frac{x}{5} = 3
