Answer 2

Ответ:

$y=3\frac{2}{5}$

Пошаговое объяснение:

$(\frac{6}{17}y-\frac{1}{5})*\frac{1}{4}=\frac{1}{4}\\\\\frac{6}{17}y-\frac{1}{5}=\frac{1}{4}:\frac{1}{4}\\\\\frac{6}{17}y-\frac{1}{5}=1\\\\ \frac{6}{17}y=1+\frac{1}{5}\\\\ \frac{6}{17}y=\frac{6}{5}\\\\y=\frac{6}{5}:\frac{6}{17}\\\\y=\frac{6}{5}*\frac{17}{6}\\\\y=\frac{17}{5}\\\\y=3\frac{2}{5}$
