|x+4|=sqrt(29)

Lösung

∣ x + 4 ∣ = 29

x = - 29 - 4 or x = 29 - 4

x = - 9.38516 \dots, x = 1.38516 \dots

Schritte zur Lösung

∣ x + 4 ∣ = 29

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

x + 4 = - 29 or x + 4 = 29

x + 4 = - 29 or x + 4 = 29

x = - 29 - 4 or x = 29 - 4

∣ x + 1 ∣ + ∣ x - 1 ∣ = x + 4

so l v e f or y, x = - 2 ∣ y ∣ - 5

x^{2} - 1 = 8

∣ 2 x - 7 ∣ = 13

∣ 2 y - 7 ∣ = ∣ 5 - 2 y ∣
