Lösung

∣ 10 x - 10 ∣ = 19

x = - \frac{9}{10} or x = \frac{29}{10}

Dezimale

x = - 0.9, x = 2.9

Schritte zur Lösung

∣ 10 x - 10 ∣ = 19

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

10 x - 10 = - 19 or 10 x - 10 = 19

10 x - 10 = - 19 or 10 x - 10 = 19

x = - \frac{9}{10} or x = \frac{29}{10}

- 78 = ∣ - 6 y ∣

3 ∣ y - 4 ∣ - 9 = 0

∣ 2 x ∣ = x + 1

ln ∣ 1 - 2 y ∣ = t + ln (4)

∣ j ∣ + 1 = - 2
