|2s+3|=11

Lösung

∣ 2 s + 3 ∣ = 11

s = - 7 or s = 4

Schritte zur Lösung

∣ 2 s + 3 ∣ = 11

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

2 s + 3 = - 11 or 2 s + 3 = 11

2 s + 3 = - 11 or 2 s + 3 = 11

s = - 7 or s = 4

∣ b + 1 ∣ = 4

∣ 2 - 3 x ∣ = ∣ x ∣

(\frac{x}{2}) + 3 = (\frac{14}{9})

so l v e f or a, ∣ 4 a - 5 b ∣ - ∣ 2 a - b ∣ = 0

3 x - x^{3} = x
