|32-6f|=20

Lösung

∣ 32 - 6 f ∣ = 20

f = 2 or f = \frac{26}{3}

Dezimale

f = 2, f = 8.66666 \dots

Schritte zur Lösung

∣ 32 - 6 f ∣ = 20

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

32 - 6 f = - 20 or 32 - 6 f = 20

32 - 6 f = - 20 or 32 - 6 f = 20

f = 2 or f = \frac{26}{3}

28 = ∣ t ∣ + 8

2 ∣ x - 8 ∣ = 14

so l v e f or x, 4 ∣ x ∣ + y = 4

so l v e f or x, 4 ∣ x ∣ + y = 0

∣ 2 x - 10 ∣ = 4
