Dezimale

x = - 0.5, x = 9.5

Schritte zur Lösung

∣ 9 - 2 x ∣ = 10

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

9 - 2 x = - 10 or 9 - 2 x = 10

9 - 2 x = - 10 or 9 - 2 x = 10

x = - \frac{1}{2} or x = \frac{19}{2}

∣ x + 10 ∣ = 3

- 9 (x^{2} - 1) = 9

∣ x - 7.5 ∣ = 3.5

6 ∣ x + 5 ∣ + 6 = 96

∣ a + 7 ∣ = 5
