| x/3-5|=1

Lösung

\frac{x}{3} - 5 = 1

x = 12 or x = 18

Schritte zur Lösung

\frac{x}{3} - 5 = 1

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

\frac{x}{3} - 5 = - 1 or \frac{x}{3} - 5 = 1

\frac{x}{3} - 5 = - 1 or \frac{x}{3} - 5 = 1

x = 12 or x = 18

∣ y - 8 ∣ + 15 = 6

- 15 = ∣ r ∣ - 7

7 = ∣ 2 x - 3 ∣

- 3 + 2 ∣ 5 x - 1 ∣ = 13

5 ∣ x - 2 ∣ - 9 = 2
