|6n+1|= 1/2

解

∣ 6 n + 1 ∣ = \frac{1}{2}

n = - \frac{1}{4} or n = - \frac{1}{12}

十進法表記

n = - 0.25, n = - 0.08333 \dots

解答ステップ

∣ 6 n + 1 ∣ = \frac{1}{2}

絶対規則を適用する:

∣ u ∣ = a, a > 0

の場合は

u = a

u = - a

6 n + 1 = - \frac{1}{2} or 6 n + 1 = \frac{1}{2}

6 n + 1 = - \frac{1}{2} or 6 n + 1 = \frac{1}{2}

n = - \frac{1}{4} or n = - \frac{1}{12}
