Schritte zur Lösung

∣ 7 x + 3 ∣ = 6

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

7 x + 3 = - 6 or 7 x + 3 = 6

7 x + 3 = - 6 or 7 x + 3 = 6

x = - \frac{9}{7} or x = \frac{3}{7}

ln ∣ 5000 - x ∣ = - 2 x

4 = m + \frac{1}{3}

so l v e f or x, ∣ x ∣ = 2 + y

2 ∣ 4 x + 9 ∣ + 1 = - 61

∣ 3 x ∣ + 3 = 30
