Schritte zur Lösung

∣ 9 - 4 n ∣ = 37

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

9 - 4 n = - 37 or 9 - 4 n = 37

9 - 4 n = - 37 or 9 - 4 n = 37

n = - 7 or n = \frac{23}{2}

∣ z ∣ + 13 = 11

so l v e f or y, 4 ∣ 2 - 9 y ∣ = 28

∣ 7 x - 19 ∣ = - 9

∣ z - 2 ∣ + ∣ z + 2 ∣ = 4

∣ 2 x + 6 ∣ = 106
