Schritte zur Lösung

∣ 7 m + 11 ∣ = 3

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

7 m + 11 = - 3 or 7 m + 11 = 3

7 m + 11 = - 3 or 7 m + 11 = 3

m = - 2 or m = - \frac{8}{7}

∣ 2 x - 1 ∣ + 8 = x

20 = ∣ - 2 + 2 c ∣

∣ 6 a + 9 ∣ + 1 = 4

2 - 5 ∣ 4 x - 10 ∣ = - 43

∣ 10 b ∣ = 10
