|1+5b|=13

Lösung

∣ 1 + 5 b ∣ = 13

b = - \frac{14}{5} or b = \frac{12}{5}

Dezimale

b = - 2.8, b = 2.4

Schritte zur Lösung

∣ 1 + 5 b ∣ = 13

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

1 + 5 b = - 13 or 1 + 5 b = 13

1 + 5 b = - 13 or 1 + 5 b = 13

b = - \frac{14}{5} or b = \frac{12}{5}

∣ 2 a - 15 ∣ = 7

1 - 3 ∣ - 7 x + 7 ∣ = - 104

∣ 4 - 2 y ∣ + 5 = 9

∣ 7 x + 3 ∣ = 2 x + 13

6 - ∣ 5 x - 10 ∣ = 4
