Dezimale

b = - 6, b = 3.5

Schritte zur Lösung

∣ - 4 b - 5 ∣ = 19

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

- 4 b - 5 = - 19 or - 4 b - 5 = 19

- 4 b - 5 = - 19 or - 4 b - 5 = 19

b = - 6 or b = \frac{7}{2}

a ∣ b x + 5 ∣ - c = d

∣ x + 4 ∣ = 3 x - 12

∣ 2 - 3 x ∣ = 2 + 3 x

18 = ∣ - 9 y ∣

4 ∣ 6 y - 1 ∣ - 6 = 6
