(24x/(100))+(23(100-x)/(100))=24.31

解

(24 \cdot \frac{x}{100}) + (23 \cdot \frac{100 - x}{100}) = 24.31

x = 131

解答ステップ

(24 \cdot \frac{x}{100}) + (23 \cdot \frac{100 - x}{100}) = 24.31

簡素化

(24 \cdot \frac{x}{100}) + (23 \cdot \frac{100 - x}{100}) : \frac{6 x}{25} + \frac{23 ( 100 - x )}{100}

\frac{6 x}{25} + \frac{23 ( 100 - x )}{100} = 24.31

LCMで乗じる

24 x + 23 (100 - x) = 2431

拡張

24 x + 23 (100 - x) : x + 2300

x + 2300 = 2431
