|2x-2|= 1/3

解

∣ 2 x - 2 ∣ = \frac{1}{3}

x = \frac{5}{6} or x = \frac{7}{6}

十進法表記

x = 0.83333 \dots, x = 1.16666 \dots

解答ステップ

∣ 2 x - 2 ∣ = \frac{1}{3}

絶対規則を適用する:

∣ u ∣ = a, a > 0

の場合は

u = a

u = - a

2 x - 2 = - \frac{1}{3} or 2 x - 2 = \frac{1}{3}

2 x - 2 = - \frac{1}{3} or 2 x - 2 = \frac{1}{3}

x = \frac{5}{6} or x = \frac{7}{6}
