| x/5+1/3 |=2

解

\frac{x}{5} + \frac{1}{3} = 2

x = - \frac{35}{3} or x = \frac{25}{3}

十進法表記

x = - 11.66666 \dots, x = 8.33333 \dots

解答ステップ

\frac{x}{5} + \frac{1}{3} = 2

絶対規則を適用する:

∣ u ∣ = a, a > 0

の場合は

u = a

u = - a

\frac{x}{5} + \frac{1}{3} = - 2 or \frac{x}{5} + \frac{1}{3} = 2

\frac{x}{5} + \frac{1}{3} = - 2 or \frac{x}{5} + \frac{1}{3} = 2

x = - \frac{35}{3} or x = \frac{25}{3}
