|2y+10|=12

Lösung

∣ 2 y + 10 ∣ = 12

y = - 11 or y = 1

Schritte zur Lösung

∣ 2 y + 10 ∣ = 12

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

2 y + 10 = - 12 or 2 y + 10 = 12

2 y + 10 = - 12 or 2 y + 10 = 12

y = - 11 or y = 1

∣ - 4 x ∣ = 3

∣ r - 6 ∣ = 32

∣ X + 5 ∣ - 3 = 1

∣ 5 x - 3 ∣ - 6 = - 2 x + 12

∣ 0.6 - 0.4 y ∣ = 2
