$$3 y - \frac { 7 } { 5 } = \frac { 35 } { 3 } - y$$
$y = \frac{49}{15} = 3\frac{4}{15} \approx 3.266666667$
$$3y-\frac{7}{5}+y=\frac{35}{3}$$
$$4y-\frac{7}{5}=\frac{35}{3}$$
$$4y=\frac{35}{3}+\frac{7}{5}$$
$$4y=\frac{175}{15}+\frac{21}{15}$$
$$4y=\frac{175+21}{15}$$
$$4y=\frac{196}{15}$$
$$y=\frac{\frac{196}{15}}{4}$$
$$y=\frac{196}{15\times 4}$$
$$y=\frac{196}{60}$$
$$y=\frac{49}{15}$$
