Schritte zur Lösung

\frac{2 x - 10}{7} = 7

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

\frac{2 x - 10}{7} = - 7 or \frac{2 x - 10}{7} = 7

\frac{2 x - 10}{7} = - 7 or \frac{2 x - 10}{7} = 7

x = - \frac{39}{2} or x = \frac{59}{2}

8 - 2 ∣ 3 n + 7 ∣ = - 54

- 5 ∣ m ∣ = 5

2 ∣ 8 x + 1 ∣ + 1 = 6

3 ∣ y + 4 ∣ - 9 = 0

∣ 2 x ∣ = 6 - x
