x+x/7+1/11 (x+x/7)=60

解

x + \frac{x}{7} + \frac{1}{11} (x + \frac{x}{7}) = 60

x = \frac{385}{8}

十進法表記

x = 48.125

解答ステップ

x + \frac{x}{7} + \frac{1}{11} (x + \frac{x}{7}) = 60

\frac{1}{11} (x + \frac{x}{7}) = \frac{x + \frac{x}{7}}{11}

x + \frac{x}{7} + \frac{x + \frac{x}{7}}{11} = 60

LCMで乗じる

96 x = 4620
