Question

2 3/5:(x+1 3/14) -1 2/5=1/3

Answer 1

Ответ:

$x=\frac{2}{7}$

Пошаговое объяснение:

$2\frac{3}{5} /(x+1\frac{3}{14} )-1\frac{2}{5} =\frac{1}{3} \\\frac{13}{5} /(x+\frac{17}{14} )-\frac{7}{5} =\frac{1}{3} \\\frac{13}{5} /\frac{14x+17}{14} -\frac{7}{5} =\frac{1}{3} \\\frac{13}{5} *\frac{14}{14x+17} -\frac{7}{5} =\frac{1}{3} \\\frac{182}{5(14x+17)} = \frac{1}{3} +\frac{7}{5} \\\frac{182}{5(14x+17)} = \frac{26}{15} \\2730 = 130(14x+17), x\neq -\frac{17}{14}\\21 = 14x+17\\14x = 4\\x = \frac{2}{7}$
