|4-x/5 |=10

Lösung

4 - \frac{x}{5} = 10

x = - 30 or x = 70

Schritte zur Lösung

4 - \frac{x}{5} = 10

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

4 - \frac{x}{5} = - 10 or 4 - \frac{x}{5} = 10

4 - \frac{x}{5} = - 10 or 4 - \frac{x}{5} = 10

x = - 30 or x = 70

2 ∣ x - 5 ∣ = 14

∣ - 9 x ∣ = 81

∣ 2 x ∣ + 19 = 13

4 = ∣ 4 c ∣

x^{2} - 2 x + 1 = x - 1
