|a-1|=1212

Lösung

∣ a - 1 ∣ = 1212

a = - 1211 or a = 1213

Schritte zur Lösung

∣ a - 1 ∣ = 1212

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

a - 1 = - 1212 or a - 1 = 1212

a - 1 = - 1212 or a - 1 = 1212

a = - 1211 or a = 1213

∣ 2 x + 7 ∣ + 11 = 3

2 x = ∣ 2 x ∣ + 4

∣ 6 x - 1 ∣ = 2

z^{2} + ∣ z ∣^{2} = 0

∣ - 2 + 6 x ∣ - 5 = - 61
