Schritte zur Lösung

\frac{b}{9} = 77

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

\frac{b}{9} = - 77 or \frac{b}{9} = 77

\frac{b}{9} = - 77 or \frac{b}{9} = 77

b = - 693 or b = 693

∣ a + 2 ∣ = 0

∣ 2 g - 5 ∣ = 9

∣ 4 X + 3 ∣ = - 3

4 ∣ 2 - 9 y ∣ = 28

5 ∣ 3 - 2 h ∣ + 21 = 6
