w = - 630 or w = - 600

Schritte zur Lösung

∣ w + 615 ∣ = 15

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

w + 615 = - 15 or w + 615 = 15

w + 615 = - 15 or w + 615 = 15

w = - 630 or w = - 600

\frac{∣ 10 + 3 k ∣}{3} = 0

∣ 3 x - 3 ∣ = 18

∣ x ∣^{2} = x

3 - (5 - ∣ x ∣) = 6

∣ 9 x + 3 ∣ = 7
