Question

Решите уравнение x+ 3 2\5=14 1\6 надо решить,

Answer 1

$x+3\frac{2}{5}=14\frac{1}{6} \\ \\ x+\frac{17}{5}=\frac{85}{6} \\ \\ x=\frac{85}{6}-\frac{17}{5} \\ \\ x= \frac{85*5-17*6}{30} =\frac{425-102}{30} = \frac{323}{30} =10 \frac{23}{30}$

Answer 2

$x+3 \frac{2}{5} =14 \frac{1}{6} \\ x=14 \frac{1}{6} -3 \frac{2}{5} \\ 14 \frac{1}{6} -3 \frac{2}{5} =14 \frac{1*5}{6*5} -3 \frac{2*6}{5*6} =14 \frac{5}{30} -3 \frac{12}{30} =13 \frac{30+5}{30} -3 \frac{12}{30} = \\ =13 \frac{35}{30} -3 \frac{12}{30} =10 \frac{23}{30} \\ \\ x=10 \frac{23}{30}$
