Schritte zur Lösung

∣ 3 (x - 3) ∣ = 7

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

3 (x - 3) = - 7 or 3 (x - 3) = 7

3 (x - 3) = - 7 or 3 (x - 3) = 7

x = \frac{2}{3} or x = \frac{16}{3}

∣ 3 (x - 3) ∣ = 8

∣ y + 5 ∣ - 7 = - 3

∣ 6 a + 1 ∣ + 19 = 4

2 = ∣ y - 9 ∣

∣ 9 (x - 8) ∣ = 27
