Question

решить целое уравнение

Answer 1

Пошаговое объяснение:

$\frac{14 - y}{8} - \frac{7y + 3}{16} = 5 \\ 2(14 - y) - (7y + 3) =80 \\ 28 - 2y - (7y + 3) = 80 \\ 28 - 2y - 7y - 3 = 80 \\ 28 - 9y - 3 = 80 \\ 25 - 9y = 80 \\ - 9y = 80 - 25 \\ - 9y = 55 \\ y = 55 \div ( - 9) \\ y = - \frac{55}{9} = - 6 \frac{1}{9}$

Answer 2

$\frac{14-y}{8}-\frac{7y+3}{16}=5\\\\\frac{28-2y}{16}-\frac{7y+3}{16}=5\\\\\frac{28-2y-7y-3}{16}=5\\\\25-9y=80\\-9y=80-25\\-9y=55\\\\ y=-\frac{55}{9} \\\\y=-6\frac{1}{9}$

Ответ: $y=-6\frac{1}{9}.$
