Schritte zur Lösung

∣ 3 a - 5 ∣ = 11

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

3 a - 5 = - 11 or 3 a - 5 = 11

3 a - 5 = - 11 or 3 a - 5 = 11

a = - 2 or a = \frac{16}{3}

3 ∣ 2 n + 7 ∣ - 12 = 3

∣ x + 12 ∣ - 16 = 2

5 - \frac{6 x}{5} = 12

∣ 5 x + 7 ∣ = 38

3 - \frac{1}{4} x = 4
