|11x+10|=22

解

∣ 11 x + 10 ∣ = 22

x = - \frac{32}{11} or x = \frac{12}{11}

十進法表記

x = - 2.90909 \dots, x = 1.09090 \dots

解答ステップ

∣ 11 x + 10 ∣ = 22

絶対規則を適用する:

∣ u ∣ = a, a > 0

の場合は

u = a

u = - a

11 x + 10 = - 22 or 11 x + 10 = 22

11 x + 10 = - 22 or 11 x + 10 = 22

x = - \frac{32}{11} or x = \frac{12}{11}
