Schritte zur Lösung

∣ 7 r + 4 ∣ = 44

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

7 r + 4 = - 44 or 7 r + 4 = 44

7 r + 4 = - 44 or 7 r + 4 = 44

r = - \frac{48}{7} or r = \frac{40}{7}

∣ x - 1 ∣ = - (x - 1)

2 \frac{1}{5} x - 2 = 8

3 ∣ 2 x - 7 ∣ = 21

∣ x ∣ = x^{2} + x - 63

2 = ∣ - g ∣
