Schritte zur Lösung

∣ x - 7 ∣ = 45

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

x - 7 = - 45 or x - 7 = 45

x - 7 = - 45 or x - 7 = 45

x = - 45 + 7 or x = 45 + 7

x^{2} - 17 ∣ x ∣ + 72 = 0

∣ 5 x - 7 ∣ - 12 = - 3

- 1 = - 4 ∣ x - 3 ∣

∣ 5 - 5 x ∣ = 2

∣ 3 a + 6 ∣ = ∣ 3 a - 8 ∣
