Schritte zur Lösung

∣ 4 x - 7 ∣ = 3

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

4 x - 7 = - 3 or 4 x - 7 = 3

4 x - 7 = - 3 or 4 x - 7 = 3

x = 1 or x = \frac{5}{2}

5 ∣ 6 - x ∣ + 9 = 34

∣ b - 9 ∣ = 20

∣ - 3 a + 8 ∣ = 11

4 - 4 ∣ 6 - 3 x ∣ = - 16

4 - 5 ∣ 10 + 5 x ∣ = - 51
