Question

решить уравнение:
4 5/14 -( х -7 3/14) = 2 9/14​

Answer 1

$4 \frac{5}{14} -(x-7 \frac{3}{14} )=2 \frac{9}{14} \\\\4 \frac{5}{14} -x+7 \frac{3}{14} -2 \frac{9}{14}=0 \\\\\frac{61}{14} +\frac{101}{14} -\frac{37}{14} =x\\x = \frac{61+101-37}{14} \\x=\frac{125}{14} \\x= 8 \frac{13}{y14}$

Ответ: $8 \frac{13}{14}$.
