Schritte zur Lösung

∣ 1.51 x + 3.28 ∣ = 2.15

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

1.51 x + 3.28 = - 2.15 or 1.51 x + 3.28 = 2.15

1.51 x + 3.28 = - 2.15 or 1.51 x + 3.28 = 2.15

x = - \frac{543}{151} or x = - \frac{113}{151}

∣ x - 10 ∣ = 17

∣ x - 10 ∣ = 12

\frac{1}{2} x + 6 = 2

3 ∣ 3 x + 2 ∣ - 8 = - 2

15 = ∣ r + 4 ∣
