Schritte zur Lösung

∣ 7 m + 2 ∣ = 5

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

7 m + 2 = - 5 or 7 m + 2 = 5

7 m + 2 = - 5 or 7 m + 2 = 5

m = - 1 or m = \frac{3}{7}

7 ∣ 9 - x ∣ + 5 = 40

8 - 7 ∣ 2 x - 1 ∣ = - 48

∣ s ∣ - 8 = 12

∣ x - 8 ∣ = \frac{x}{3}

2 ∣ 5 x + 10 ∣ - 1 = 13
